NCIt definition : Insulin-like growth factor 1 receptor (1367 aa, 155 kDa) is encoded by the human
IGF1R gene. This protein is involved in cell proliferation and apoptosis inhibition.;
NCIt note : Insulin-like growth factor-1 receptor is a membrane-bound protein, processed to form
disulfide-linked alpha2/beta2 tetramer. It binds both insulin growth factors I and
II. Ligand binding activates protein kinase activity, controls cell cycle progression
and enhances cell survival.;
