    • Introduction

      Obestatin is a hormone that is produced in the cells lining the stomach and small intestine of several mammals including humans; it drastically reduces appetite in mice and is expected to do the same in humans. Obestatin is a peptide hormone - a relatively small protein. It is encoded by the same gene that also encodes ghrelin, a peptide hormone that increases appetite. The protein produced by that gene breaks into two smaller peptides, ghrelin and obestatin. Ghrelin is an endogenous ligand for the growth hormone secretagogue receptor and is involved in regulating growth hormone release. Ghrelin is derived from a preprohormone called preproghrelin, which also generates a second peptide called obestatin. Ghrelin is an endogenous ligand for the orphan G protein-coupled receptor GPR39 and is involved in satiety and decreased food intake.

    • Background

      Transforming Growth Factor Beta Receptor 1 (TGFBR1), a transmembrane protein crucial in the TGF-β signaling pathway, holds a paramount position in regulating diverse cellular processes. Its intricate involvement in development, immune responses, tissue homeostasis, and disease has elevated TGFBR1 to a central role in biology and medicine. This research embarks on a comprehensive exploration of the TGFBR1 protein, unraveling its structural complexities, signaling mechanisms, and its far-reaching implications in various physiological and pathological contexts. By dissecting the intricacies of TGFBR1, scientists aim to decode the fundamental cellular processes it governs and explore potential therapeutic avenues in the domains of cancer, fibrosis, and immunology.

      Structural Complexity of TGFBR1:

      TGFBR1 is a serine/threonine kinase receptor with an extracellular ligand-binding domain, a transmembrane domain, and an intracellular kinase domain. Its structure allows it to interact with TGF-β ligands and initiate downstream signaling cascades. Understanding the three-dimensional architecture of TGFBR1 is pivotal for deciphering its interactions with ligands, co-receptors, and intracellular signaling partners, shedding light on the molecular intricacies of its function.

      Signaling Pathways and Physiological Functions:

      Upon ligand binding, TGFBR1 phosphorylates downstream effectors, regulating processes like cell proliferation, differentiation, apoptosis, and immune responses. TGF-β signaling mediated by TGFBR1 is vital in embryogenesis, tissue repair, and immune tolerance. Dysregulation of this pathway is implicated in numerous diseases, including cancer, fibrosis, and autoimmune disorders, underscoring the significance of TGFBR1 in maintaining cellular and tissue homeostasis.

      TGFBR1 in Cancer Biology:

      TGFBR1's dual role as a tumor suppressor and a promoter of cancer progression reflects its complexity in cancer biology. In early stages, TGFBR1 signaling suppresses cell growth and promotes apoptosis, acting as a defense against tumorigenesis. However, in advanced stages, cancer cells exploit TGFBR1 signaling to facilitate invasion, metastasis, and immune evasion. Understanding the context-dependent nature of TGFBR1's functions in cancer is pivotal for developing targeted therapies.

      Targeting TGFBR1 in Therapeutics:

      Given its critical roles in various diseases, TGFBR1 has emerged as an attractive target for therapeutic interventions. In cancer, efforts are underway to develop small molecule inhibitors and monoclonal antibodies that modulate TGFBR1 signaling, aiming to curb tumor progression. Additionally, in fibrotic disorders, targeting TGFBR1 offers hope for halting the pathological tissue remodeling characteristic of these diseases, providing potential treatments for conditions such as pulmonary fibrosis and liver cirrhosis.

      TGFBR1 Protein, with its intricate signaling mechanisms and diverse physiological roles, stands at the crossroads of fundamental cellular processes and disease pathogenesis. Its involvement in development, immune regulation, cancer, and tissue homeostasis underscores its significance in biology and medicine. As researchers delve deeper into the complexities of TGFBR1, they pave the way for innovative therapies and a deeper understanding of diseases, ultimately shaping the future of healthcare and scientific exploration. This research not only illuminates the pivotal role of TGFBR1 but also holds the promise of transformative advancements in medicine and our understanding of cellular signaling pathways.

    • Introduction

      The secreted polypeptide noggin, encoded by the NOG gene, binds and inactivates members of the transforming growth factor-beta (TGF-beta) superfamily signaling proteins, such as bone morphogenetic protein-4 (BMP4). By diffusing through extracellular matrices more efficiently than members of the TGF-beta superfamily, noggin may have a principal role in creating morphogenic gradients. Noggin appears to have pleiotropic effect, both early in development as well as in later stages. It was originally isolated from Xenopus based on its ability to restore normal dorsal-ventral body axis in embryos that had been artificially ventralized by UV treatment. The results of the mouse knockout of noggin suggest that it is involved in numerous developmental processes, such as neural tube fusion and joint formation. Recently, several dominant human NOG mutations in unrelated families with proximal symphalangism (SYM1) and multiple synostoses syndrome (SYNS1) were identified; both SYM1 and SYNS1 have multiple joint fusion as their principal feature, and map to the same region (17q22) as NOG. All NOG mutations altered evolutionarily conserved amino acid residues. The amino acid sequence of human noggin is highly homologous to that of Xenopus, rat and mouse.

    • Physical Appearance

      Sterile Filtered White lyophilized (freeze-dried) powder.

    • Stability

      Lyophilized Mouse Noggin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Mouse Noggin should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.

    • Solubility

      It is recommended to be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in 10mM HAc to a concentration of 0.1-1.0 mg/ml. Further dilutions should be made in appropriate buffered solutions.
