Supplementary information

VASP also known as Vasodilator-Stimulated Phosphoprotein is a 46-50 kDa protein involved in actin filament assembly and elongation. It plays an important role in cellular motility and the maintenance of cell shape. VASP is expressed in many cell types but is notably present in platelets and endothelial cells. It is an important player in signal transduction pathways that lead to cytoskeletal reorganization influencing cell movement and adhesion dynamics.
Biological function summary

VASP is an important component in cell movement regulation. It acts within a larger complex of actin-binding proteins that control the assembly of actin filaments. This protein influences cell adhesion migration and signal transduction processes. Through these actions VASP influences cellular responses to environmental cues making it essential for cellular dynamics and integrity during development and wound healing.

Pathways

VASP connects to significant signaling pathways such as the PI3K/Akt pathway and the cAMP pathway. It often interacts with proteins like c-Abl tyrosine kinase and Mena contributing to actin dynamics regulation. These pathways are critical for transducing signals from extracellular environments to intracellular responses allowing for coordinated cellular functions in processes such as cell migration and growth.

VASP plays a role in cardiovascular disease and cancer-related metastasis due to its function in cell motility and adhesion. Abnormal VASP activity is associated with impaired endothelial cell function and contributes to atherosclerosis development. Additionally it interacts with proteins like Mena and fascin in cancer cells aiding in metastatic progression by enhancing motility and invasive capabilities.

General info

Function

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.

Sequence similarities

Belongs to the Ena/VASP family.

Post-translational modifications

Major substrate for cAMP-dependent (PKA) and cGMP-dependent protein kinase (PKG) in platelets. The preferred site for PKA is Ser-157, the preferred site for PKG/PRKG1, Ser-239. In ADP-activated platelets, phosphorylation by PKA or PKG on Ser-157 leads to fibrinogen receptor inhibition. Phosphorylation on Thr-278 requires prior phosphorylation on Ser-157 and Ser-239. In response to phorbol ester (PMA) stimulation, phosphorylated by PKC/PRKCA. In response to thrombin, phosphorylated by both PKC and ROCK1. Phosphorylation at Thr-278 by AMPK does not require prior phosphorylation at Ser-157 or Ser-239. Phosphorylation at Ser-157 by PKA is required for localization to the tight junctions in epithelial cells. Phosphorylation modulates F-actin binding, actin filament elongation and platelet activation. Phosphorylation at Ser-322 by AMPK also alters actin filament binding. Carbon monoxide (CO) promotes phosphorylation at Ser-157, while nitric oxide (NO) promotes phosphorylation at Ser-157, but also at Ser-239. Response to NO and CO is blunted in platelets from diabetic patients, and VASP is not phosphorylated efficiently at Ser-157 and Ser-239.
