Leptin Antagonist Triple Mutant Human Recombinant is Mono-Pegylated with 20kDa PEG and was purified by proprietary chromatographic techniques.

    Source

    Escherichia coli.

    Formulation

    The protein was lyophilized from a concentrated (0.65mg/ml) solution with 0.003mM NaHCO3.

    Purity

    Greater than 98.0% as determined by:
    (a) Gel filtration analysis.
    (b) Analysis by SDS-PAGE.

    Biological Activity

    Capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Its in vitro activity is 6-8 fold lower than the non-pegylated antagonist but in vivo it has profound weight gain effect (as compared to the non-pegylated antagonist), resulting mainly from increased food intake. Its in vivo activity compared to that of PEG-MLA is 9-27 fold higher.

This research paper aims to provide a comprehensive analysis of LL-37, elucidating its biochemical properties, antimicrobial activity, immunomodulatory effects, and potential therapeutic applications.

      LL-37, derived from the precursor protein hCAP18, plays a crucial role in innate immunity and host defense against microbial pathogens. Beyond its well-established antimicrobial properties, LL-37 exhibits various immunomodulatory effects, making it an intriguing target for therapeutic interventions (Lai & Gallo, 2009). This paper aims to delve into the complexities of LL-37, uncovering its multifaceted nature and potential clinical applications.

      LL-37 is a cationic peptide characterized by a helical structure that facilitates its interaction with microbial membranes. Its amphipathic nature enables it to penetrate microbial membranes, leading to disruption and subsequent cell death (Zaiou, 2007). Additionally, LL-37 can undergo proteolytic processing to release smaller bioactive fragments with distinct functions (Bowdish et al., 2005).

      LL-37's antimicrobial activity extends beyond direct microbial killing. It also exhibits immunomodulatory effects, stimulating the recruitment of immune cells and promoting the clearance of pathogens through phagocytosis (Scott et al., 2002). Furthermore, LL-37 can neutralize endotoxins, reducing inflammation caused by microbial products (Davidson et al., 2004).

      LL-37 possesses immunomodulatory properties that influence various immune cells, including neutrophils, macrophages, dendritic cells, and lymphocytes (Nagaoka et al., 2001). It can promote the differentiation and maturation of immune cells, modulate cytokine production, and contribute to wound healing and tissue repair (van Harten et al., 2018).

      The multifunctional nature of LL-37 renders it a promising candidate for various therapeutic applications.

    • Introduction

      Protein disulfide isomerases (PDIs) constitute a family of structurally related enzymes which catalyze disulfide bonds formation, reduction, or isomerization of newly synthesized proteins in the lumen of the endoplasmic reticulum (ER). They act also as chaperones, and are, therefore, part of a quality-control system for the correct folding of the proteins in the same subcellular compartment. PDI has been found to have moderate effects (25-fold) on the rate of oxidative folding of proteins in vitro.

    More Info

    • Introduction

      Listeriolysin O (aka LLO) is a hemolysin produced by Listeria monocytogenes bacteria, the pathogen responsible for causing listeriosis. The toxin may be regarded as a virulence factor, since it is crucial for the virulence of L. monocytogenes. LLO is a single polypeptide protein encoded by the hlyA gene and composed of 529 residues. LLO is a thiol-activated cholesterol-dependent pore forming toxin protein; therefore, it is activated by reducing agents and inhibited by oxidizing agents. Still, LLO differs from other thiol-activated toxins, as its cytolytic activity is maximized at a pH of 5.5. Inside the acidic phagosomes (average pH ~ 5.9) of cells that have phagocytosed L. monocytogenes, LLO is selectively activated by maximizing activity at a pH of 5.5. Following the phagosome lysis by LLO, the bacterium breaks out into the cytosol, where it is able to grow intracellularly, and the toxin has reduced activity in the more basic cytosol. Thus, LLO permits L. monocytogenes to break out from the phagosomes into the cytosol without harming the plasma membrane of the infected cell, which allows the bacteria to live intracellularly, where they are sheltered from extracellular immune system factors such as the complement system and antibodies. LLO also brings about dephosphorylation of histone H3 and deacetylation of histone H4 in the early phases of infection, before entry of L. monocytogenes into the host cell. The pore-forming activity is not implicated in causing the histone modifications. The modifications of the histones affect the down regulation of genes encoding proteins involved in the inflammatory response. Therefore, LLO may be significant in subverting the host immune response to L. monocytogenes. At its NH2-terminus it possesses a 25 residues long typical signal sequence excited during the secretion process. Moreover, in its NH2-terminus there is also a 19 amino acids PEST- like sequence that may target this toxin for degradation. The PEST-like sequence found in LLO and is considered crucial for virulence, given that mutants lacking the sequence lysed the host cell. Nevertheless, contrary to PEST's supposed role in protein degradation, evidence implies that the PEST-like sequence may control LLO production in the cytosol rather than increase degradation of LLO.

    More Info

    • Introduction

      Apolipoprotein E (APOE) is a chylomicron lipoprotein which is essential for the metabolism of lipoproteins and lipid transport. The APOE gene has 3 alleles, designated APOE2, APOE3, and APOE4. The APOE allelic proteins differ by only one or two amino acids, however have different biological structures and functions. APOE3 is the most common and neutral allele. The APOE4 allele is linked with an increased risk for Alzheimer's Disease (AD) and coronary artery disease (CAD). The APOE4 protein morphology decreases the ability of APOE4 to clear beta-amyloid protein from the brain, resulting in AD progression. The APOE2 allele is linked with type III hyperlipoproteinemia, which is characterized by defects in the clearance of plasma lipoproteins, however APOE2 may have a protective effect against AD.

    More Info

    • Introduction

      Clusterin also named Apolipoprotein J (APO-J) is a 75-80 kD disulfide-linked heterodimeric protein containing about 30% of N-linked carbohydrate rich in sialic acid but truncated forms targeted to the nucleus have also been identified.
      The precursor polypeptide chain is cleaved proteolytically to remove the 22-mer secretory signal peptide and subsequently between residues 227/228 to generate the a and b chains. These are assembled in anti-parallel to give a heterodimeric molecule in which the cysteine-rich centers are linked by five disulfide bridges and are flanked by two predicted coiled-coil a-helices and three predicted amphipathic a-helices.
      Across a broad range of species clusterin shows a high degree of sequence homology ranging from 70% to 80%. It is nearly ubiquitously expressed in most mammalian tissues and can be found in plasma, milk, urine, cerebrospinal fluid and semen.
      It is able to bind and form complexes with numerous partners such as immunoglobulins, lipids, bacteria, complement components, paraoxonase, beta amyloid, leptin and others. Clusterin has been ascribed a plethora of functions such as phagocyte recruitment, aggregation induction, complement attack prevention, apoptosis inhibition, membrane remodeling, lipid transport, hormone transport and/or scavenging, matrix metalloproteinase inhibition.
      A genuine function of clusterin has not been defined. One tempting hypothesis says that clusterin is an extracellular chaperone protecting cells from stress induced insults caused by degraded and misfolded protein precipitates.
      Clusterin is up- or down regulated on the mRNA or protein level in many pathological and clinically relevant situations including cancer, organ regeneration, infection, Alzheimer disease, retinitis pigmentosa, myocardial infarction, renal tubular damage, autoimmunity and others.

    • Background

      Thyroglobulin, a glycoprotein primarily produced in the thyroid gland, stands at the center of thyroid hormone synthesis. Comprising a series of tyrosine residues, thyroglobulin serves as the scaffold upon which thyroid hormones are assembled. Beyond its pivotal role in thyroid physiology, thyroglobulin has garnered significant attention in the realm of thyroid disease diagnostics, offering valuable insights into thyroid function and disorders. This research delves into the intricacies of thyroglobulin human recombinant protein, exploring its biochemical properties, physiological significance, and its crucial applications in both clinical and research settings.

      Structural Complexity of Thyroglobulin:

      Thyroglobulin is a large, dimeric protein boasting an intricate structure composed of multiple domains. Within its structure lie tyrosine residues crucial for iodine incorporation, a process fundamental for thyroid hormone synthesis. Its size and complexity reflect the sophistication of thyroid hormone production, as thyroglobulin acts as a reservoir for thyroid hormones within the thyroid follicles.

      Physiological Significance in Thyroid Function:

      Thyroglobulin plays a central role in the synthesis of triiodothyronine (T3) and thyroxine (T4), the thyroid hormones essential for regulating metabolism and overall body homeostasis. During thyroid hormone synthesis, thyroglobulin is secreted into the follicular lumen, where it undergoes iodination and subsequent proteolysis, releasing T3 and T4. This process highlights the indispensable nature of thyroglobulin in thyroid hormone production, making it a key biomolecule in thyroid physiology.

    • Introduction

      AHSG (fetuin-A) which is a glycoprotein present in the serum, is synthesized by hepatocytes. AHSG is one of the fetuin class of plasma binding proteins. It is involved in a number of functions, such as endocytosis, brain development and the formation of bone tissue. It is usually present in the cortical plate of the immature cerebral cortex and bone marrow hemopoietic matrix, hence it has been postulated that it participates in the development of the tissues. Yet, its exact significance is still vague. AHSG promotes endocytosis, hold opsonic properties and influences the mineral phase of the bone. Affinity for calcium and barium ions has been shown.

    Purity

    Greater than 95% as determined by SDS-PAGE.

    More Info

    • Introduction

      PDCD6 is a calcium-binding protein and is a member of the penta-EF-hand protein family. Calcium binding is vital for homodimerization and for conformational changes essential for binding to other protein partners. PDCD6 takes part in T cell receptor-, Fas-, and glucocorticoid-induced programmed cell death. However, tests showed that in mice deficient for PDCD6, apoptosis was not blocked which suggests that PDCD6 is functionally redundant.

    More Info

    • Introduction

      Mannose-6-Phosphate Receptor (M6PR) belongs to the P-type lectin family. P-type lectins play a vital role in lysosome function through the specific transport of mannose-6-phosphate-containing acid hydrolases from the Golgi complex to lysosomes. The M6PR protein functions as a homodimer and needs divalent cations for ligand binding. Lysosomal enzymes carrying phosphomannosyl residues bind specifically to mannose-6-phosphate receptors in the Golgi apparatus and the ensuing receptor-ligand complex is transferred to an acidic prelyosomal compartment where the low pH mediates the dissociation of the complex.

    More Info

    • Introduction

      Clusterin also known as Apolipoprotein J (APO-J) is a 75-80 kD disulfide-linked heterodimeric protein containing about 30% of N-linked carbohydrate rich in sialic acid but truncated forms targeted to the nucleus have also been identified.
      The precursor polypeptide chain is cleaved proteolytically to remove the 22-mer secretory signal peptide and subsequently between residues 227/228 to generate the a and b chains. These are assembled in anti-parallel to give a heterodimeric molecule in which the cysteine-rich centers are linked by 5 disulfide bridges and are flanked by 2 predicted coiled-coil a-helices and 3 predicted amphipathic a-helices.
      Across a broad range of species clusterin shows a high degree of sequence homology ranging from 70% -80%. It is nearly ubiquitously expressed in most mammalian tissues and can be found in plasma, milk, urine, cerebrospinal fluid and semen.
      It is able to bind and form complexes with numerous partners such as immunoglobulins, lipids, heparin, bacteria, complement components, paraoxonase, beta amyloid, leptin and others. Clusterin has been ascribed a plethora of functions such as phagocyte recruitment, aggregation induction, complement attack prevention, apoptosis inhibition, membrane remodeling, lipid transport, hormone transport and/or scavenging, matrix metalloproteinase inhibition.
      Clusterin is up/down regulated on the mRNA or protein level in many pathological and clinically relevant situations including cancer, organ regeneration, infection, Alzheimer disease, retinitis pigmentosa, myocardial infarction, renal tubular damage, autoimmunity and others.

    More Info

    • Introduction

      AHSG (fetuin-A) which is a glycoprotein present in the serum, is synthesized by hepatocytes. AHSG is one of the fetuin class of plasma binding proteins. It is involved in a number of functions, such as endocytosis, brain development and the formation of bone tissue. It is usually present in the cortical plate of the immature cerebral cortex and bone marrow hemopoietic matrix, hence it has been postulated that it participates in the development of the tissues. Yet, its exact significance is still vague. AHSG promotes endocytosis, hold opsonic properties and influences the mineral phase of the bone. Affinity for calcium and barium ions has been shown.

    • Introduction

      ANGPT1 is an angiogenic factor which intervenes in blood vessel maturation and takes part in endothelial development. ANGPT1 is a secreted ligand for Tie-2, a cell surface receptor tyrosine kinase expressed in endothelial and hemopoietic cells. The glycosylated ANGPT1 protein has a coiled-coil region in the amino terminus and a fibrinogen-like domain at the carboxy terminus.

    • Synonyms

      Angiopoietin 1, KIAA0003, ANG-1, AGP1, AGPT.

    • Physical Appearance

      Sterile Filtered colorless solution.

    • Stability

      Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.

    • Background

      This factor was found in the conditioned medium of the human neuroepithelioma cell line SHEP1 and the mouse myoblast cell line C2C12ras. The cDNA encoding a protein of 498 amino acids was isolated by using a secretion-trap expression cloning procedure exploiting the presence of a signal sequence present in growth factors that are secreted by producer cells (Davis et al, 1996). Murine and human factors show 97 % identity at the amino acid level. For a related factor see: CDT6. The human gene has been mapped to chromosome 8q22.3-q23 (Cheung et al, 1998).

      The expression of angiopoietin-1 mRNA is downregulated by PDGF, EGF, IL1-beta, and TGF-beta (Enholm et al, 1997).

      Angiopoietin-1 is a ligand for the receptor-like tyrosine kinase designated TIE-2 (Davis et al, 1996). Binding of Angiopoietin-1 to its receptor induces tyrosine phosphorylation of the cytoplasmic receptor domain. A naturally occuring antagonist of Angiopoietin-1 binding to TIE-2 is Angiopoietin-2. Angiopoietin-1 also binds to the TIE-1 receptor and this interaction appears to be critical for the development of the right-hand side venous system. It is dispensable for the left-hand side venous system, suggesting that right-hand and left-hand side vascular networks are established early before asymmetrical features of the network become morphologically discernible Loughna and Sato, 2001).

      Angiopoietin-1 does not directly promote the growth of cultured endothelial cells. Angiopoietin-1 is chemotactic for endothelial cells (Witzenbichler et al, 1998). Excess soluble TIE-2 receptors abolish the chemotactic response of endothelial cells toward angiopoietin-1. Angiopoietin-1 has been shown to counteract cell death by apoptosis in cultured endothelial cells (Holash et al, 1999). Angiopoietin-1 also acts as an apoptosis survival factor for endothelial cells and this effect is augmented by the presence of VEGF (Kwak et al, 1999).

      Angiopoietin-2 dose-dependently blocks directed migration toward Angiopoietin-1. Carlson et al (2001) have shown that Ang-1 binds rather selectively to vitronectin and that Ang-1 can directly support adhesion of human umbilical vein endothelial cells and fibroblasts in a process mediated by integrins.

      The physiologic roles of Angiopoietin-1 and its receptor are limited to angiogenic processes that occur subsequent to the earlier vasculogenic and angiogenic actions of the VEGF family and their receptors. However, it is unlike most of the known angiogenesis factors such as VEGF and other classical endothelial cell growth factors in that addition of the factor to cultures of endothelial cells does not directly promote cell growth even though the TIE-2 receptor becomes activated. Angiopoietin-1 also appears to be incapable of inducing the formation of tubules by endothelial cells.

      Angiopoietins can potentiate the effects of other angiogenic cytokines. An investigation of the impact of angiopoietins on neovascularization in vivo in the cornea micropocket assay of neovascularization demonstrates that neither Angiopoietin-1 nor Angiopoietin-2 alone promote neovascularization. Holash et al (1999) have shown that a subset of tumors initially grows by coopting existing host vessels. Regression of these vessels via a process that involves disruption of interactions between endothelial cells and smooth muscle cells as well as cell death by apoptosis of endothelial cells first causes loss of tumour cells before angiogenesis begins at the tumor margin and the tumor is rescued under the influence of VEGF, Angiopoietin-1, and probably other angiogenic stimuli.

      The embryonic expression pattern of Angiopoietin-1 suggests that it plays a particularly important role in the developing heart. Angiopoietin-1 is expressed highly in the myocardial wall surrounding the endocardium expressing TIE-2. Expression of Angiopoietin-1 becomes much more widespread later in development.

    • Introduction

      Annexin A11 (ANXA11) belongs to the annexin family, which is a group of calcium-dependent phospholipid-binding proteins. Annexins have distinctive N-terminal domains and conserved C-terminal domains, which contain the calcium-dependent phospholipid-binding sites. Annexin A11 binds specifically to calcyclin in a calcium-dependent manner. Moreover, ANXA11 is required for midbody formation and completion of the terminal phase of cytokinesis. The ANXA11 protein is a 56kDa antigen recognized by sera from patients with various autoimmune diseases.
