Description: Members of the glial cell line-derived neurotrophic factor (GDNF) family, including GDNF and Neurturin, play key roles in the control of vertebrate neuronal survivial and differentiation. GDNF is a glycosylated, disulfide-bonded homodimer that is distantly related to the TGF superfamily of growth factors. Three receptors for these factors, GFR alpha-1, GFR alpha-2, and GFR alpha-3 have been identified. The receptors do not contain transmembrane domains and are attached to the cell membrane by glycosyl-phosphoinositol linkage. Both GFR alpha-1 and GFR alpha-2 have been shown to mediate the GDNF-dependent and Neurturin-dependent phosphorylation and activation of the tyrosine kinase Ret. GFR-3 is expressed only during development. GFR alpha-2 binds Neurturin and mediates activation of RET receptor tyrosine kinase by both Neurturin and GDNF.

Description: The three mammalian isoforms of TGF-β, TGF-β1, β2, β3, signal through the same receptor and elicit similar biological responses. They are multifunctional cytokines that regulate cell proliferation, growth, differentiation and motility as well as synthesis and deposition of the extracellular matrix. They are involved in various physiological processes including embryogenesis, tissue remodeling and would healing. They are secreted predominantly as latent complexes which are stored at the cell surface and in the extracellular matrix. The release of biologically active TGF-β isoform from a latent complex involves proteolytic processing of the complex and /or induction of conformational changes by proteins such as thrombospondin-1. The physiological role of TGF-β3 is still unknown but its expression pattern suggests a role in the regulation of certain development processes. Recombinant TGF-β3 is a 25.0 kDa protein composed of two identical 112 amino acid polypeptide chains linked by a single disulfide bond.Manufactured using all non-animal reagents.

Description: Somatostatin [SST, GHIH (growth hormone-inhibiting hormone) or SRIF (somatotropin release-inhibiting factor)] is a cyclic peptide hormone existing as two isoforms and produced in the pancreas islet, GI tract and the central nervous system. Tetradecapeptide Somatostatin-14 (SRIF-14, the originally identified somatostatin) and the 28-amino acid Somatostatin-28 (SRIF-28) have similar biological activities but differ in their potency. Somatostatins regulate the endocrine system: they inhibit the release of growth hormone in contrast to Growth Hormone Factor (GRF), which stimulates the release of growth hormone. They also inhibit the release of prolactin and thyrotropin, peptide hormones from the pituitary gland and glucagon and insulin from the pancreas. They control the secretion of gut hormones and function as neurotransmitters.

Description: The IGFs are mitogenic polypeptide growth factors that stimulate the proliferation and survival of various cell types including muscle, bone, and cartilage tissue in vitro. IGFs are predominantly produced by the liver, although a variety of tissues produce the IGFs at distinctive times. The IGFs belong to the Insulin gene family, which also contains insulin and relaxin. The IGFs are similar by structure and function to insulin, but have a much higher growth-promoting activity than insulin. IGF-II expression is influenced by placenta lactogen, while IGF-I expression is regulated by growth hormone. Both IGF-I and IGF-II signal through the tyrosine kinase type I receptor (IGF-IR), but, IGF-II can also signal through the IGF-II/Mannose-6-phosphate receptor. Mature IGFs are generated by proteolytic processing of inactive precursor proteins, which contain N-terminal and C-terminal propeptide regions. Recombinant human IGF-I and IGF-II are globular proteins containing 70 and 67 amino acids, respectively, and 3 intra-molecular disulfide bonds.
