      UniProt Number
      UniProt SummaryFUNCTION: 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.
