| Specificity / Sensitivity | Phospho-IRS-1 (Ser 302) Antibody detects endogenous levels of IRS-1 only when phosphorylated at Ser302 of mouse IRS-1 or Ser307 of human IRS-1. This antibody does not detect IRS-1 phosphorylated at other sites. |
| Source / Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser 302 of mouse IRS-1. Antibodies are purified by protein A and peptide affinity chromatography. Western Blotting
Western blot analysis of extracts from CHO IR/IRS-1 cells ( transfected with insulin receptor and IRS-1), untreated or insulin-treated (100 nM for 5 min), showing an increase in phospho-IRS-1 (Ser302) with insulin stimulation, using Phospho-IRS1 (Ser302) Antibody. To confirm phospho-specificity of the antibody, a duplicate membrane was treated with calf intestinal alkaline phosphatase (CIP) after Western transfer. |
| Background | 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 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). Ser302 in rat/mouse IRS-1 (corresponding to Ser307 of human 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 (11).
