- Extra Details:
- 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, which 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) and Ser789 was phosphorylated by SIK-2, a member of AMPK family (7). The phosphorylation of Ser612 and Ser636/639 is mediated by the PKC and mTOR pathways, respectively (8, 9), resulting in an inhibition of insulin signaling in the cell and suggesting a potential mechanism for insulin resistance in some models of obesity. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1:1000, incubate membrane with diluted antibody in TBS, 5% BSA, 0.1% Tween-20 at 4°C with gentle shaking, overnight. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
