Description_x000D_ General description_x000D_ Vasodilator stimulated phosphoprotein (VASP) is encoded by the gene mapped to human chromosome 19q13.32. The encoded protein belongs to the Ena/VASP protein family. VASP is characterized with an N-terminal EVH1 domain, C-terminal EVH2 domain and proline-rich region._x000D_ Immunogen_x000D_ synthetic peptide containing phosphorylated Ser157 of human VASP. The corresponding sequence is highly conserved (single amino acid substitution) in mouse and rat VASP._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide_x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Vasodilator stimulated phosphoprotein (VASP) acts as an actin-polymerization regulator and plays a vital role in regulation of cell migration by interacting with Migfilin, a cell-extracellular matrix (ECM) adhesion protein. Elevated expression of VASP contributes to the development of breast cancer (BC). Hence, this protein can be used as a potential biomarker for BC metastasis. Phosphorylation of VASP by protein kinase A (PKA) at phosphorylation site S157 aids in localization of cell periphery into focal adhesions, but phosphorylation of VASP at S239 and T278 aids in regulation of F-actin assembly.
