IRS1 antibody (pSer307)

Catalog No. ABIN129580

Product Details anti-IRS1 Antibody

Target: IRS1 (Insulin Receptor Substrate 1 (IRS1))

Binding Specificity: AA 298-316, pSer307

Reactivity: Human

Host: Rabbit

Clonality: Polyclonal

Conjugate: This IRS1 antibody is un-conjugated

Application: Western Blotting (WB), ELISA

Characteristics: Concentration Definition: by UV absorbance at 280 nm

Immunogen: This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to amino acids 298-316 of human IRS1 protein.

Isotype: IgG

Application Details

Application Notes: This affinity purified antibody has been tested for use in ELISA and western blot.  Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 130 kDa in size corresponding to phosphorylated IRS1 protein by western blotting in the appropriate cell lysate or extract.   Minimal reactivity is observed against the non-phosphorylated form of the immunizing peptide.  This antibody is phospho specific for pS307 of IRS1 protein.

Restrictions: For Research Use only

Background: Insulin Receptor Substrate 1 (IRS1) acts as a signaling molecule for IL-4, insulin and insulin-like growth factor-I (IGF-I) receptors.  When phosphorylated by the insulin receptor, IRS1 binds specifically to various cellular proteins containing SH2 domains such as phosphatidylinositol 3-kinase p85 subunit or GRB2.  When bound, IRS1 typically activates phos-phatidylinositol 3-kinase p85 subunit.  IRS1 interacts with both the NPXY motif of tyrosine-phos-phorylated IGF1R and the INSR through the PTB domain.  Serine phosphorylation of IRS1 is a mechanism for insulin resistance. Ser-312 phosphorylation inhibits insulin action through disruption of IRS1 interaction with the
