Inhibits IGF-mediated growth and developmental rates. 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. Binds IGF2 more than IGF1. Note: This description may include information from UniProtKB.
Molecular Function: insulin-like growth factor I binding; insulin-like growth factor II binding; protein binding
Biological Process: aging; cellular protein metabolic process; cellular response to hormone stimulus; female pregnancy; positive regulation of activated T cell proliferation; regulation of cell growth; regulation of insulin-like growth factor receptor signaling pathway; response to drug; response to estradiol stimulus; response to glucocorticoid stimulus; response to lithium ion; response to mechanical stimulus; response to nutrient; response to retinoic acid; signal transduction
LTP: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
