VASP(Phospho-Ser157) Antibody

Description

Product Name VASP(Phospho-Ser157) Antibody
Host Species Rabbit
Clonality Polyclonal
Purification Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.
Applications WB IHC
Species Reactivity Hu Rt
Specificity The antibody detects endogenous level of VASP only when phosphorylated at serine 157.
Immunogen Type Peptide-KLH
Immunogen Description Peptide sequence around phosphorylation site of serine 157 (R-V-S(p)-N-A) derived from Human VASP.
Target Name VASP

Background

Ena/VASP proteins are actin-associated proteins involved in a range of processes dependent on cytoskeleton remodeling and cell polarity such as axon guidance, lamellipodial and filopodial dynamics, platelet activation and cell migration. VASP promotes actin filament elongation. It protects the barbed end of growing actin filaments against capping and increases the rate of actin polymerization in the presence of capping protein. VASP stimulates actin filament elongation by promoting the transfer of profilin-bound actin monomers onto the barbed end of growing actin filaments. Plays a role in actin-based mobility of Listeria monocytogenes in host cells. Regulates actin dynamics in platelets and plays an important role in regulating platelet aggregation.
