UniProtKB - A6XND0 (A6XND0_HUMAN)
Protein
Insulin-like growth factor-binding protein 3
Gene
IGFBP3
Organism
Homo sapiens (Human)
Status
Functioni
IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors. Also exhibits IGF-independent antiproliferative and apoptotic effects mediated by its receptor TMEM219/IGFBP-3R.ARBA annotation
Caution
Lacks conserved residue(s) required for the propagation of feature annotation.PROSITE-ProRule annotation
