Synonyms:
Insulin-like growth factor 1, Insulin-like growth factor I, IGF-I, Somatomedin
Description:
Insulin-like growth factor I (IGF-I) is a growth factor that is produced by the liver. IGF-I production is stimulated by growth hormone (GH). IGF-I binds the insulin-like growth factor I receptor (IGF-I receptor) and the insulin receptor to stimulate systemic body growth. IGF-I is one of the most potent activators of the AKT signaling pathway, which stimulates cell proliferation and inhibits programmed cell death. Mature human IGF-I shares 100% homology with bovine and porcine IGF-I.
