Background: IRS1

Human IRS1 (insulin receptor substrate 1) is a 160-180 kDa substrate that transmits signals from the insulin and IGF-I receptor to downstream signaling modulators. The 1242 amino acid (aa) human IRS1 contains a PH domain (aa 12-115), a PTB domain (aa 160-263) and ten PEST sequences (aa 340-1225). IRS1 may be proteolytically cleaved at Arg656-Val657, generating a 90 kDa and 79 kDa fragment. Upon insulin/IGF-I receptor activation, IRS1 is tyrosine phosphorylated, allowing its association with PI-3 kinase and GRB2. Phosphorylation on Y612 and Y632 is important for IRS1 to fully activate PI3K and translocate GLUT4 in respose to insulin. The sequence surrounding pTyr612 is identical between human and mouse IRS1.
