Background: Insμlin receptor substrate 1 (IRS-1) is one of the major substrates of the insμlin receptor kinase. IRS-1 contains mμltiple tyrosine phosphorylation motifs that serve as docking sites for SH2-domain containing proteins that mediate the metabolic and growth-promoting functions of insμlin. 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 resμlts in an inhibition of insμlin signaling in the cell, suggesting a potential mechanism for insμlin resistance in some models of obesity.
