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 (2-4). IRS-1 also contains over 30 potential serine\/threonine phosphorylation sites. Ser307 of IRS-1 is phosphorylated by JNK (5) and IKK (6) while Ser789 is phosphorylated by SIK-2, a member of the AMPK family (7). The PKC and mTOR pathways mediate phosphorylation of IRS-1 at Ser612 and Ser636\/639, respectively (8,9). 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 (10). Phosphorylation of IRS-1 at Ser612 by MAPK downregulates insulin signaling and may be part of a response to high glucose\/glucosamine levels (11).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nHIRS-1; Insulin receptor substrate 1; IRS-1; IRS1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 180\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800971169961,"sku":"3203T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-3203t","provider":"Iright","version":"1.0","type":"link"}
