Background Information Insulin Receptor substrate proteins are the effectors of both Insulin and IGF-initiated signaling. They share PH and PTB domains near their n-termini, and multiple Tyr phosphorylation motifs in their c-terminal regions. Proteins which bind to tyrosine-phosphorylated IRS-proteins include PI3 Kinase p85, GRB2, SHP2, Nck, Crk, and Fyn. IRS1 appears to be principally involved in IGF-signaling and cytoskeletal growth. IRS2 appears to be the critical mediator of Insulin signaling, as genetic ablation results in type II diabetes. IRS3 is expressed primarily in adipocytes and is an unusually potent activator of PI3 Kinase. IRS4 lacks the tyrosine residues which in the other IRS-proteins binds to SHP2.

UniProt Number
UniProt Summary FUNCTION: SwissProt: P35568 # 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).
SIZE: 1242 amino acids; 131591 Da
SUBUNIT: Interacts with the NPXY motif of tyrosine-phosphorylated IGF1R and INSR via the PTB domain. Binds to phosphatidylinositol 3-kinase p85 subunit via the phosphorylated YXXM motifs. Binds ROCK1. Binds to UBTF and PIK3CA in nuclear extracts (By similarity). Interacts with SOCS7.
PTM: Serine phosphorylation of IRS1 is a mechanism for insulin resistance. Ser-312 phosphorylation inhibits insulin action through disruption of IRS1 interaction with the insulin receptor (By similarity). & Phosphorylation of Tyr-896 is required for GRB2-binding (By similarity).DISEASE:SwissProt: P35568 # Polymorphisms in IRS1 may be involved in the etiology of non-insulin-dependent diabetes mellitus (NIDDM) [MIM:125853].
SIMILARITY: SwissProt: P35568 ## Contains 1 IRS-type PTB domain. & Contains 1 PH domain.
