NCIt definition : Insulin-like growth factor I (195 aa, 22 kDa) is encoded by the human IGF1 gene.
This protein may be involved in the regulation of glucose metabolism.;
NCIt note : Similar to insulin, the full length insulin-like growth factor I precursor protein
is cleaved at positions 48 and 188 to release a 70 amino acid growth factor and a
77 amino acid E peptide. (UniProt); Elevated serum levels of insulin-like growth factor-1 (IGF-1) may identify premenopausal
women who are likely to develop breast cancer before age 50. (Int J Cancer. 2000;
