Anti-Vasodilator Stimulated Phosphoprotein (VASP)

VASP (vasodilator stimulated phosphoprotein) plays an important role in ANF/NO/cGMP Protein kinase and cAMP/cAMP Protein kinase signalling pathways. VASP is expressed in almost all human and animal cell lines, particularly high concentrations are found in thrombocytes, vascular smooth muscle cells and fibroblasts. In cultured cells VASP is associated with focal contacts, cell-cell-contacts, microfilaments and dynamic membrane regions such as the leading edge. In vitro binding data show that VASP binds to profilin, zyxin, vinculin, and the Listeria spp. surface protein ActA. Functional evidence indicates that VASP is a crucial factor involved in the enhancement of actin filament formation. Ser 157 is a site preferred by cAMP-dependent protein kinase (PKA). Applications: Suitable for use in ELISA and Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1:500-1:1000, Optimal dilutions to be determined by the researcher. Storage and Stability: For long-term storage, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
