| Description | Human IGF-BP3, also known as growth-hormone-dependant binding protein, is 28.9 kDa cysteine-rich secreted protein. It is the major IGF binding protein present in the plasma of human and animals and it is also found in alpha-granules of platelets. In addition to its ability to modulate the activity of IGF-I and IGF-2, IGF-BP3 exerts inhibitory effects on follicle stimulating hormone (FSH) activity. Decreased plasma levels of IGF-BP3 often results in dwarfism, whereas elevated levels of IGF-BP3 may lead to acromegaly. The expression of IGF-BP3 in fibroblasts is stimulated by mitogenic growth factors such as Bombesin, Vasopressin, PDGF and EGF. Recombinant human IGF-BP3 is a 28.8 kDa protein consisting of 264 amino acid residues. |
