Insulin Receptor Substrate 1 (IRS1) acts as a signaling molecule for IL-4, insulin and insulin-like growth factor-I (IGF-I) receptors. When phosphorylated by the insulin receptor, IRS1 binds specifically to various cellular proteins containing SH2 domains such as phosphatidylinositol 3-kinase p85 subunit or GRB2. When bound, IRS1 typically activates phos-phatidylinositol 3-kinase p85 subunit. IRS1 interacts with both the NPXY motif of tyrosine-phos-phorylated IGF1R and the INSR through the PTB domain. Serine phosphorylation of IRS1 is a mechanism for insulin resistance. Diseases associated with IRS1 include Diabetes Mellitus, Noninsulin-Dependent and Mixed Cell Adenoma. Anti-IRS1pS307 is useful for researchers interested in protein kinase binding, IL-2 pathways, and RET signaling.
