    Protocol

    Specificity / Sensitivity

    Phospho-Gab1 (Tyr307) Antibody detects endogenous levels of Gab1 only when phosphorylated at tyrosine 307. The antibody cross-reacts with phosphorylated Gab2 and may also cross-react with phosphorylated Gab3. The antibody may cross-react with activated receptor tyrosine kinases (RTKs).

    Species Reactivity:

    Human, Mouse

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr307 of human Gab1. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    The Grb-associated binder (Gab) family is a family of adaptor proteins recruited by a wide variety of receptor tyrosine kinases (RTKs) such as EGFR, HGFR, insulin receptor, cytokine receptor and B cell antigen receptors. Upon stimulation of RTKs by their cognate ligand, Gab is recruited to the plasma membrane where it is phosphorylated and functions as a scaffold (1-4). Multiple tyrosine phosphorylation sites of Gab1 protein have been identified (5). Phosphorylation of Tyr472 regulates its binding to p85 PI3 kinase (6,7). Phosphorylation of Gab1 at Tyr307, Tyr373 and Tyr407 modulates its association to PLCγ (8). Phosphorylation of Tyr627 and Tyr659 is required for Gab1 binding to and activation of the protein tyrosine phosphatase SHP2 (6,9).
