IRS-1 is phosphorylated on serine, threonine and tyrosine residues in a variety of tissues. An insulin-sensitive serine\/threonine kinase casein kinase II mediates a portion of the insulin-stimulated serine\/threonine phosphorylation of overexpressed IRS-1 in vivo. Thr 502 is identified as the major casein kinase II-catalyzed phosphorylation site in rat IRS-1, and Ser 99 is an additional phosphorylation site catalyzed by casein kinase II. Thus, casein kinase II-catalyzed phosphorylation of IRS-1 may be a component of the intracellular insulin signaling cascade. IRS-1 contains three putative binding sites for 14-3-3 (Ser 270, Ser 374 and Ser 641) and the motif around Ser 270 is located in the phosphortyrosine binding domain of IRS-1, which is responsible for the interaction with the insulin receptor.\u003c\/p\u003e \n\n\u003cp\u003eProduct: Rabbit IgG, 1mg\/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2\u003c\/p\u003e\n\n\u003cp\u003ePurification and Purity: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is \u0026gt; 95% (by SDS-PAGE).\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: IRS-1 (R301) polyclonal antibody detects endogenous levels of IRS-1 protein\u003c\/p\u003e\n\n\u003cp\u003eNote: For research use only, not for use in diagnostic procedure.\u003c\/p\u003e\n\n\u003cp\u003eExtra Notes: Western blot (WB) analysis of IRS-1 (R301) polyclonal antibody at 1:500 dilution\u003cbr\u003e\nLane 1: HEK293T whole cell lysate\u003cbr\u003e\nLane 2: Raw264.7 whole cell lysate\u003cbr\u003e\nLane 3: PC12 whole cell lysate, Immunohistochemistry (IHC) analyzes of IRS-1 (R301) pAb in paraffin-embedded human breast carcinoma tissue at 1:100.\u003c\/p\u003e \n\n\u003cp\u003eBioworld Molecular Weight: ~180 kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
