View All» Molecular Weight: ~160 kDa observed. This protein has several post-translational modifications; therefore, the molecular weight will vary between ~150-170 kDa. View All» Epitope: Phosphorylated Ser318 View All» Immunogen: KLH-conjugated linear peptide corresponding to mouse IRS1 when phosphorylated at Ser318. View All» Clone: 3.1.1 View All» Isotype: IgG1κ View All» Background Information: IRS1 (Insulin Receptor Substrate 1) transmits insulin signals via metabolic and mitogenic pathways. IRS1 is heavily phosphorylated on both serine and tyrosine residues. These phosphorylated tyrosines enable IRS to act as a docking protein that binds SH2 domains of such proteins as PI3 Kinase (phosphatidylinositol 3-kinase) and GRB2, resulting in activation. Over expression and phosphorylation of serine is associated with insulin resistance and breast cancer. Some of the more notable phosphorylation sites are Ser302 that is phosphorylated following insulin stimulation. Ser307, phosphorylated by JNK and IKK, is a key regulatory site that appears to disrupt the IRS1/IR interaction and inhibits insulin-mediated activation of the PI3 kinase and MAPK pathways, and Ser636/639 that is known to be phosphorylated by p70S6K downstream of mTOR and acts as a negative feedback loop.

View All» Key Applications: Western Blotting View All» UniProt Summary: FUNCTION: May mediate the control of various cellular processes by insulin. When phosphorylated by the insulin receptor binds specifically to various cellular proteins containing SH2 domains such as phosphatidylinositol 3-kinase p85 subunit or GRB2. Activates phosphatidylinositol 3-kinase when bound to the regulatory p85 subunit (By similarity).SUBUNIT STRUCTURE: Interacts (via phosphorylated YXXM motifs) with PIK3R1 (By similarity). Interacts with ROCK1 (By similarity). Interacts with GRB2 (By similarity). Interacts with SOCS7 (By similarity). Interacts (via IRS-type PTB domain) with IGF1R and INSR (via the tyrosine-phosphorylated NPXY motif) (By similarity). Interacts with UBTF and PIK3CA. Interacts (via PH domain) with PHIP. TISSUE SPECIFICITY: Expressed in osteoblasts, but not in osteoclasts. PTM: Serine phosphorylation of IRS1 is a mechanism for insulin resistance. Ser-307 phosphorylation inhibits insulin action through disruption of IRS1 interaction with the insulin receptor (By similarity).Phosphorylation of Tyr-891 is required for GRB2-binding (By similarity).SEQUENCE SIMILARITIES; Contains 1 IRS-type PTB domain.Contains 1 PH domain.
