| Gene Description | Insulin receptor substrate 1 is one of the major substrates of the insulin receptor kinase. IRS-1 contains multiple tyrosine phosphorylation motifs that serve as docking sites for SH2-domain containing proteins that mediate the metabolic and growth-promoting functions of insulin. IRS-1 also contains over 30 potential serine/threonine phosphorylation sites. Ser307 of IRS-1 is phosphorylated by JNK and IKK while Ser789 is phosphorylated by SIK-2, a member of the AMPK family. The PKC and mTOR pathways mediate phosphorylation of IRS-1 at Ser612 and Ser636/639, respectively. Phosphorylation of IRS-1 at Ser1101 is mediated by PKCθ and results in an inhibition of insulin signaling in the cell, suggesting a potential mechanism for insulin resistance in some models of obesity.Ser302 in rat/mouse IRS-1 is phosphorylated rapidly during insulin stimulation and has a postive role in IRS-1 tyrosine phosphorylation. Inhibition of Ser302 phosphorylation by short-term amino acid/glucose starvation correlates with a decrease in IRS-1 tyrosine phosphorylation without inhibition of insulin receptor autophosphorylation or Akt phosphorylation. A defect in this positive regulatory pathway may be a mechanism contributing to insulin resistence. |
