Anti-phospho-VASP [pThr²⁷⁸] antibody produced in rabbit

VASP is localized at highly dynamic membrane regions, focal adhesion sites, lamellipodia protrusions, filopodia tips, and along stress fibers. It is also localized at cell-matrix and cell-cell contacts.

Vasodilator-stimulated phosphoprotein (VASP) is located on human chromosome 19q13.32. It belongs to enabled (Ena) family of proteins and encodes a protein of 46 kDa. VASP has three domain organisation, that is, an N-terminal Ena/VASP (EVH1) homology domain, proline rich central domain and EVH2 actin binding domain.

synthetic peptide containing phosphorylated Thr²⁷⁸ of human VASP, conjugated to KLH. The corresponding sequence is identical in mouse and rat VASP.

Anti-phospho-VASP [pThr278] antibody produced in rabbit may be used in immunoblotting and immunoprecipitation.

Anti-phospho-VASP [pThr278] specifically recognizes human VASP phosphorylated at Thr278.

Regulation of phosphorylation of Vasodilator-stimulated phosphoprotein (VASP) is observed during actin cytoskeleton formation. It promotes protrusion and propulsion speed and inhibits branching of actins. It plays a key role in the signal transduction pathway related to neutrophil spreading.

VASP plays an important role in cell motility and adhesion. This protein is also involved in adherens junction formation and stabilization in epithelial cells. VASP is a substrate for cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP)-dependent protein kinases. VASP is required for endothelial barrier function in vivo. Knockout of VASP proteins in mice leads to increased endothelial permeability causing fatal vascular leakage and hemorrhage during late embryonic development.

Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide.

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers,is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
