Summary of IGFBP3
IGFBP3 (insulin like growth factor binding protein 3) encodes a protein that forms a complex with insulin-like growth factor acid-labile subunit (IGFALS) and either insulin-like growth factor 1 or 2 (R).
Polymorphisms of this can cause cancer (R).
The Function of IGFBP3
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.
