Lett. 22:869-876(2015). CC -!- FUNCTION: IGF-binding proteins prolong the half-life of the IGFs and CC have been shown to either inhibit or stimulate the growth promoting CC effects of the IGFs on cell culture. They alter the interaction of IGFs CC with their cell surface receptors. Also exhibits IGF-independent CC antiproliferative and apoptotic effects mediated by its receptor CC TMEM219/IGFBP-3R. Inhibits the positive effect of humanin on insulin CC sensitivity (PubMed:19623253). Promotes testicular germ cell apoptosis CC (PubMed:19952275). {ECO:0000269|PubMed:19623253, CC ECO:0000269|PubMed:19952275, ECO:0000269|PubMed:20353938}. CC -!- SUBUNIT: Interacts with XLKD1 (By similarity). Binds IGF2 more than CC IGF1. Forms a ternary complex of about 140 to 150 kDa with IGF1 or IGF2 CC and a 85 kDa glycoprotein (ALS). Interacts with humanin; humanin CC competes with importin KPNB1 for binding to IGFBP3, blocking IGFBP3 CC nuclear import and IGFBP3-mediated apoptosis (PubMed:14561895, CC PubMed:19623253, PubMed:26216267). Interacts with TMEM219. CC {ECO:0000250, ECO:0000269|PubMed:14561895, ECO:0000269|PubMed:1726837, CC ECO:0000269|PubMed:19623253, ECO:0000269|PubMed:20353938, CC ECO:0000269|PubMed:26216267}.

Present in plasma. CC -!- DEVELOPMENTAL STAGE: IGFBP3 levels are higher during extrauterine life CC and peak during puberty. CC -!- INDUCTION: Up-regulated in the presence of IGF1, insulin and other CC growth-stimulating factors such as growth hormone, EGF and phorbol CC esters. CC -!- DOMAIN: The thyroglobulin type-1 domain mediates interaction with HN. CC -!- PTM: Phosphorylated by FAM20C in the extracellular medium. CC {ECO:0000269|PubMed:26091039}.
