    Product Information

    Product Usage Information

    Application Dilution
    Western Blotting 1:1000

    Storage

    Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

    Protocol

    Specificity / Sensitivity

    Phospho-VASP (Ser239) Antibody detects endogenous levels of VASP only when phosphorylated at serine 239. The antibody does not cross-react with phosphorylated VASP homologues, such as Mena.

    Species Reactivity:

    Human, Mouse, Rat, Monkey

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser239 of human VASP. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    Vasodilator-stimulated phosphoprotein (VASP) was originally characterized as a substrate of both cGMP- and cAMP-dependent kinases (PKG and PKA, or cGPK and cAPK, respectively) (1). It is now believed that VASP belongs to the Ena/VASP family of adaptor proteins linking the cytoskeletal system to the signal transduction pathways and that it functions in cytoskeletal organization, fibroblast migration, platelet activation, and axon guidance (2,3). Three phosphorylation sites, Ser157, Ser239, and Thr278, have been identified. Ser239 is the major PKG phosphorylation site, while Ser157 is the major PKA phosphorylation site (4). Evidence suggests that VASP phosphorylation reduces its association with actin and has a negative effect on actin polymerization (5). Phosphorylation at Ser239 of VASP is a useful marker for monitoring PKG activation and signaling (6,7).
