Recombinant Human Insulin-like Growth Factor Binding Protein 3
Insulin-like Growth Factor-Binding Protein 3 (IGFBP3) belongs to the IGFBP family, which are all proteins with conserved cysteine residues, an IGFBP domain, and a thyroglobulin type-I domain. IGFBP3 is expressed by most tissues and is the most abundant IGFBP protein. It has higher levels of expression during postnatal life, which peak during puberty. The expression of IGFBP3 in fibroblasts is stimulated by a number of mitogenic growth factors. The protein forms a ternary complex with IGFI or IGFII, and an acid-labile subunit, causing it to circulate in the plasma. As this complex, it prolongs the half-life of IGFs and alters their interaction with cell surface receptors. Decreased plasma levels of IGFBP3 often happen during the progression of prostate cancer from benign to metastatic disease.
