IGFBP3蛋白背景綜述
Insulin-like growth factor-binding proteins (IGFBPs) prolong the half-life of the IGFs, control bioavailability, activity, and distribution of insulin-like growth factor (IGF) through high-affinity IGFBP/IGF complexes. Six high-affinity IGF-binding proteins (IGFBP-1 to -6) have been identified. Human IGFBP3 is a widely expressed protein containing an IGFBP domain at the N-terminus and a thyroglobulin type-I domain. IGFBP3 forms a ternary complex of about 140 ~150 kDa with IGF1 or IGF2 and a glycoprotein insulin-like growth factor acid-labile subunit (ALS), thus alter the interaction of IGFs with their cell surface receptors. IGFBP3 exerts either proapoptotic or growth stimulatory effects depending upon the cellular context. Studies have shown that IGFBP3 can leads to the induction of apoptosis dependent or independent of the IGF-IGF receptor axis, accordingly acts as a negative regulator of tumorigenesis and progressing in certain carcinomas. In addition, IGFBP3 also interacts with the Alzheimer's survival peptide humanin (HN), playing a role in neurological disease processes.
