MyBioSource.com's IRS1 Polyclonal Antibody is a Rabbit Polyclonal antibody. This antibody has been shown to work in applications such as: Western Blot. The IRS1 Polyclonal Antibody was generated using HIRS-1, Insulin Receptor Substrate 1, and IRS1 as the antigen and it reacts with Human, Mouse, and Rat.
Description
Insulin receptor substrate 1 (IRS-1) is one of the major substrates of the insulin receptor kinase (1). 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 PKCtheta and results in an inhibition of insulin signaling in the cell, suggesting a potential mechanism for insulin resistance in some models of obesity (10)
