Applications Key: W=Western Blotting, IP=Immunoprecipitation
Reactivity Key: H=Human, M=Mouse, R=Rat, Mk=Monkey
After the primary antibody is bound to the target protein, a complex with HRP-linked secondary antibody is formed. The LumiGLO® is added and emits light during enzyme catalyzed decomposition.
Western blot analysis of extracts from CHO IR/4PS cells (transfected with insulin receptor and IRS-2) or CHO IR/IRS-1 cells (transfected with insulin receptor and IRS-1), showing no change in total protein levels with insulin stimulation (100 nM for 5 min), using IRS-2 Antibody (top) or IRS-1 Antibody #2382 (bottom).
Western blot analysis of MCF-7 cell extracts, unstimulated and insulin-stimulated (100 nM for 5 min), using IRS-1 Antibody #2382 (left) and Phospho-IRS-1 (Ser307) Antibody (right).
Western blot analysis of cell extracts from CHO IR/IRS-1 cells, untreated or treated with insulin, using Phospho-IRS-1 (Ser612) (C15H5) Rabbit mAb (upper and middle) or IRS-1 Antibody #2382 (lower). The middle blot was treated with calf intestinal phosphatase (CIP) before antibody probing.
Western blot analysis of MCF7, C2C12 and RD cell lines using IRS-1 (D23G12) Rabbit mAb.
Western blot analysis of extracts from serum-starved C2C12 cells, untreated or insulin-treated (150 nM for 5 min.), using Phospho-IRS-1 (Ser318) (D51C3) Rabbit mAb (upper), or IRS-1 Antibody #3407 (lower).
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).
