Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
Vasodilator-stimulated phosphoprotein (VASP), a substrate for cAMP- and cGMP-dependent kinases, is associated with actin filaments, focal adhesions, and dynamic membrane regions. VASP is composed of several distinct domains: a central L-proline-rich domain contains a GPPPPP motif as a single copy and as a three-fold tandem repeat, as well as three conserved phosphorylation sites for cyclic nucleotide-dependent protein kinases (Ser157, Ser239, and Thr278). A C-terminal domain contains a repetitive mixed-charge cluster which is predicted to form an α-helix. The C-terminal domain appears to be responsible for anchoring at focal adhesion sites. VASP has been shown to be a ligand for profilins. Profilins bind to the poly-L-proline motifs of VASP and it is postulated that these two molecules act in concert to convey signal transduction to actin filament formation.
