More Info

Introduction
Endothelial cells express three different vascular endothelial growth factor (VEGF) receptors, belonging to the family of receptor tyrosine kinases (RTKs). They are named VEGFR-1 (Flt-1), VEGFR-2 (KDR/Flk-1), and VEGFR-3 (Flt-4). Their expression is almost exclusively restricted to endothelial cells, but VEGFR-1 can also be found on monocytes. All VEGF-receptors have seven immunoglobulin-like extracellular domains, a single transmembrane region and an intracellular split tyrosine kinase domain. VEGFR-2 has a lower affinity for VEGF than the Flt-1 receptor, but a higher signalling activity. Mitogenic activity in endothelial cells is mainly mediated by VEGFR-2 leading to their proliferation. Differential splicing of the flt-1 gene leads to the formation of a secreted, soluble variant of VEGFR-1 (sVEGFR-1). No naturally occurring, secreted forms of VEGFR-2 have so far been reported. The binding of VEGF165 to VEGFR-2 is dependent on heparin.

More Info

Introduction
IL4 is a pleiotropic cytokine produced by activated T cells. IL4 is a ligand for interleukin 4 receptor. The interleukin 4 receptor also binds to IL13, which may contribute to many overlapping functions of this cytokine and IL13. STAT6, a signal transducer and activator of transcription, has been shown to play a central role in mediating the immune regulatory signal of this cytokine. This gene, IL3, IL5, IL13, and CSF2 form a cytokine gene cluster on chromosome 5q, with this gene particularly close to IL13. IL4, IL13 and IL5 are found to be regulated coordinately by several long-range regulatory elements in an over 120 kilobase range on the chromosome. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported.

More Info

Introduction
Prolactin is a pituitary hormone that plays a role in the stimulation of milk production, salt and water regulation, growth, development and reproduction. The primary step in its action is the binding to a specific membrane receptor (prolactin receptor) which belongs to the superfamily of class 1 cytokine receptors. Prolactin is a hormone involved in a range of significant functions including ion transport and osmoregulation, stimulation of milk, protein synthesis as well as the regulation of numerous reproductive functions. Prolactin exerts its influence on different cell types through a signal transduction pathway which begins with the binding of the hormone to a transmembrane Prolactin receptor. PRLR varies in size (short and long forms) with tissue source and species, from ~40 kDa to 100 kDa. The PRL-R consists of at least 3 separate domains: an extracellular region with 5 cysteines which contains the prolactin binding site, a single transmembrane domain and a cytoplasmic region, the length of which appears to influence ligand binding and regulate cellular function.
Synonyms
PRL-R, hPRLrI.
Physical Appearance
Sterile filtered white lyophilized powder.
Stability

Background
VEGFR-1 (Vascular Endothelial Growth Factor Receptor-1), also known as Flt-1 (Fms-like tyrosine kinase 1), is a critical receptor involved in angiogenesis and vascular development. This research paper delves into the structure, function, and therapeutic implications of VEGFR-1, shedding light on its multifaceted role in various physiological and pathological processes.
VEGFR-1 is a transmembrane receptor tyrosine kinase belonging to the VEGF receptor family. It is primarily expressed on endothelial cells and plays a pivotal role in mediating the cellular responses to VEGF ligands. Upon ligand binding, VEGFR-1 initiates intracellular signaling cascades that regulate endothelial cell proliferation, migration, and survival, ultimately contributing to the formation of new blood vessels.
The structure of VEGFR-1 comprises distinct domains, including an extracellular ligand-binding domain, a transmembrane domain, and an intracellular tyrosine kinase domain. The extracellular domain facilitates the interaction between VEGF ligands and the receptor, while the intracellular domain transduces downstream signals by phosphorylating specific tyrosine residues.
VEGFR-1 exhibits not only ligand-dependent but also ligand-independent functions. In addition to its role as a VEGF receptor, it can act as a decoy receptor, sequestering VEGF and modulating the bioavailability of VEGF ligands. This unique property allows VEGFR-1 to regulate VEGF signaling and influence angiogenic processes.
The signaling pathways activated by VEGFR-1 are diverse and intricate, involving multiple downstream effectors, such as PI3K/AKT, MAPK/ERK, and STAT proteins. These pathways regulate endothelial cell behaviors, including proliferation, migration, and differentiation, which are crucial for angiogenesis. Perturbations in VEGFR-1 signaling have been implicated in various pathological conditions, including cancer, retinopathy, and inflammatory disorders.
The therapeutic targeting of VEGFR-1 has gained considerable attention for its potential in managing angiogenesis-related diseases. Inhibitors specifically designed to block VEGFR-1 have been developed to suppress aberrant angiogenesis and impede tumor growth. Moreover, VEGFR-1-based therapies have been explored for ocular diseases like wet age-related macular degeneration (AMD) and diabetic retinopathy, aiming to alleviate pathological neovascularization.
The availability of VEGFR-1 human recombinant proteins has facilitated in-depth research and the development of potential therapeutic interventions. Recombinant VEGFR-1 proteins serve as valuable tools for investigating VEGF-VEGFR-1 interactions, screening drug candidates, and elucidating the underlying molecular mechanisms of VEGFR-1-mediated signaling pathways.

Introduction
KIT, also known as KIT Proto-Oncogene Receptor Tyrosine, is a cytokine receptor which is expressed not only in hematopoietic stem cells but likewise in other cell types. KIT binds to receptor tyrosine kinase type III, which is a stem cell factor, also named a "rigid factor" or "c-kit ligand". Once this receptor binds to stem cell factor (SCF), it forms a dimer which activates intrinsic tyrosine kinase activity, which sequentially phosphorylates & activates signaling molecules which breed signals in cells. This receptor protects vascular smooth muscle cells from apoptosis in addition to restoring cardiac function after myocardial infarction.

Introduction
Glia Maturation Factor-Beta (GMF-Beta) is a 17 kDa protein nerve gorwth factor identified as a growth and differentiation factor in the vertebrate brain.
Glia Maturation Factor-Beta stimulates differentiation of normal neurons as well as glial cells. GMFB inhibits the proliferation of the N-18 neuroblastoma line and the C6 glioma line while promoting their phenotypic expression.
GMF-beta inhances the phenotypic expression of glia & neurons thus inhibits the proliferation of their respective tumors when added to cell culture. Although astrocytes produce GMF-b and stores it inside the cells, they don’t secrete the GMF-B into the cultured medium. Cell- surface GMFb acts on the target cells at close range when cells are in direct contact. GMF-Beta is produced by thymic epithelial cells and plays an important role in T cell development in favor of CD4+ T cells.
GMF-Beta is a brain-specific protein which belongs to the actin-binding proteins (ADF) family. GMF-beta appears to play a role in the differentiation, maintenance, and regeneration of the nervous system. It also supports the progression of certain auto-immune diseases, possibly through its ability to induce the production and secretion of various pro-inflammatory cytokines.
Synonyms
Glia maturation factor beta, GMFB, GMF-B, GMF-beta, GMF.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Stability

They are named VEGFR-1 (Flt-1), VEGFR-2 (KDR/Flk-1), VEGFR-3 (Flt-4). Their expression is almost exclusively restricted to endothelial cells, but VEGFR-1 can also be found on monocytes, dendritic cells and on trophoblast cells. The flt-1 gene was first described in 1990. The receptor contains seven immunoglobulin-like extracellular domains, a single transmembrane region and an intracellular splited tyrosine kinase domain. Compared to VEGFR-2 the Flt-1 receptor has a higher affinity for VEGF but a weaker signaling activity. VEGFR-1 thus leads not to proliferation of endothelial cells, but mediates signals for differentiation. Interestingly a naturally occuring soluble variant of VEGFR-1 (sVEGFR-1) was found in HUVE supernatants in 1996, which is generated by alternative splicing of the flt-1 mRNA. The biological functions of sVEGFR-1 still are not clear, but it seems to be an endogenous regulator of angiogenesis, binding VEGF with the same affinity as the full-length receptor.
Synonyms
FLT-1, FLT1, Tyrosine-protein kinase receptor FLT, Flt-1, Tyrosine-protein kinase FRT, Fms-like tyrosine kinase 1, VEGFR-1.
Physical Appearance

More Info

Introduction
Galectin-4 is a member of the subfamily of galectins composed of two carbohydrate recognition domains having similar peptide chains. The galectins are a family of beta-galactoside-binding proteins having a role in modulating cell-cell and cell-matrix interactions, which inhibits chronic inflammations, GVHD, and allergic responses. LGALS4 expression is limited to small intestine, colon, and rectum, and it is underexpressed in colorectal cancer. LGALS4 binds as an endogenous ligand to glycosphingolipids having 3-O-sulfated Gal residues and bind as well to cholesterol-3-sulfate. LGALS4 takes part in cell adhesion. LGALS4 plays a role in crosslinking the lateral cell membranes of the surface-lining epithelial cells, thus supporting epithelial integrity against mechanical stress exerted by the bowel lume. LGALS4 is in charge of intestinal inflammation via selective regulation of peripheral and mucosal T-cell cell cycle, in addition to cell death by apoptosis of T-cells by a pathway independent of the activation of caspases. LGALS4 blockade decreases TNF-alpha inhibitor induced T-cell death. LGALS4 decreases pro-inflammatory cytokine secretion including IL-6 & IL-17.

More Info

Introduction
Nephroblastoma Overexpressed (NOV) is a member of the CCN family of secreted cysteine rich regulatory proteins. The full length NOV protein is comprised of 4 structural domains, which present distinct, and sometimes opposing, biological activities. An elevated expression of NOV is linked with certain tumors, including Wilm’s tumor and most nephroblastomas. On the other hand, in other tumor types and certain cancer cell lines, increased tumorgenicity and proliferation is associated with decreased NOV expression.

Background
Pro-Nerve Growth Factor Human Recombinant: Unveiling its Potential in Neuroregulation and Disease Pathogenesis
Abstract:
Pro-Nerve Growth Factor (Pro-NGF) human recombinant is a crucial precursor protein involved in neuronal development, survival, and degenerative processes. This research paper aims to provide a comprehensive analysis of Pro-NGF, including its characteristics, processing mechanisms, and implications in neuroregulation and disease pathogenesis. Additionally, innovative methodologies for the production and manipulation of Pro-NGF human recombinant are proposed, highlighting its potential as a therapeutic target for neurological disorders and neurodegenerative diseases.
Introduction:
Neuroregulation and maintenance of neuronal health are intricate processes governed by a network of signaling molecules. Pro-NGF, the precursor form of Nerve Growth Factor (NGF), acts as a key player in neuronal development, synaptic plasticity, and cell survival. This paper delves into the distinctive features of Pro-NGF and presents novel approaches for the production and manipulation of Pro-NGF human recombinant, aiming to unravel its role in neuroregulation and disease pathogenesis.
Characteristics and Processing Mechanisms:
Pro-NGF is initially synthesized as an inactive precursor, requiring proteolytic cleavage for conversion into mature NGF. The processing of Pro-NGF involves the action of proteases, such as furin, and the formation of distinct protein complexes. The balance between Pro-NGF and mature NGF levels plays a critical role in modulating neuronal function and fate, influencing processes such as neuronal survival, axonal growth, and synaptic plasticity.
Production and Manipulation of Pro-NGF Human Recombinant:
Efficient production methodologies and manipulation strategies are crucial for studying the role of Pro-NGF in neuroregulation and disease pathogenesis. Recombinant protein expression systems, including mammalian cell culture and bacterial expression systems, have been employed to produce functional Pro-NGF human recombinant. Techniques such as mutagenesis, protein purification, and specific inhibitors targeting Pro-NGF processing pathways enable the manipulation of Pro-NGF levels and investigation of its downstream effects.
Implications in Neuroregulation and Disease Pathogenesis:
Pro-NGF human recombinant holds significant potential in understanding the intricate mechanisms underlying neuroregulation and disease pathogenesis. Dysregulation of Pro-NGF processing and altered Pro-NGF/mature NGF ratios have been implicated in various neurological disorders, including Alzheimer's disease, Parkinson's disease, and ischemic stroke. Manipulating Pro-NGF levels and the balance between its mature form may offer therapeutic strategies for modulating neurotrophic signaling and promoting neuronal health in these conditions.
Conclusion:
Pro-NGF human recombinant emerges as a key regulator in neuroregulation and disease pathogenesis, offering promising avenues for therapeutic intervention. Enhancing our understanding of Pro-NGF processing mechanisms and its downstream signaling cascades will provide valuable insights into neurodevelopment, neurodegeneration, and potential therapeutic strategies. Targeting Pro-NGF as a therapeutic intervention may hold immense promise in treating neurological disorders and promoting neuronal health.
