Protein Information
Name IRS1
Function May mediate the control of various cellular processes by insulin. When phosphorylated by the insulin receptor binds specifically to various cellular proteins containing SH2 domains such as phosphatidylinositol 3-kinase p85 subunit or GRB2. Activates phosphatidylinositol 3-kinase when bound to the regulatory p85 subunit (By similarity).

IRS-1 (Insulin receptor substrate-1) is phosphorylated in response to stimulation of cells by insulin. Upon ligand-induced phosphorylation, IRS-1 immediately associates with a series of SH2 domain-containing signaling intermediates such as PI3-kinase, GRB2, Syp and Nck. The level of diversity in structure and function of the SH2-containing proteins which binds activated IRS-1 is important for responsiveness to insulin. IRS phosphorylation elicits the growth and metablic effects of insulin growth factors and insulin by allowing glucose uptake, glycogen synthesis and mitogenic activity. IRS-1 migrates between 170 and 185 kDa and is expressed in most cell types.
