'''HUMAN VASP TETRAMERISATION DOMAIN'''<br />

==Overview==

==human VASP tetramerisation domain==
-
The vasodilator-stimulated phosphoprotein (VASP) is a key regulator of, actin dynamics. We have determined the 1.3-A resolution crystal structure, of the 45-residue-long tetramerization domain (TD) from human VASP. This, domain forms a right-handed alpha-helical coiled-coil structure with a, similar degree of supercoiling as found in the widespread left-handed, coiled coils with heptad repeats. The basis for the right-handed geometry, of VASP TD is a 15-residue repeat in its amino acid sequence, which, reveals a characteristic pattern of hydrophobic residues. Hydrophobic, interactions and a network of salt bridges render VASP TD highly, thermostable with a melting point of 120 degrees C.

== Function ==
 +
[https://www.uniprot.org/uniprot/VASP_HUMAN VASP_HUMAN] 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.<ref>PMID:7828592</ref> <ref>PMID:10087267</ref> <ref>PMID:10438535</ref> <ref>PMID:15939738</ref> <ref>PMID:17082196</ref> <ref>PMID:18559661</ref>

The vasodilator-stimulated phosphoprotein (VASP) is a key regulator of actin dynamics. We have determined the 1.3-A resolution crystal structure of the 45-residue-long tetramerization domain (TD) from human VASP. This domain forms a right-handed alpha-helical coiled-coil structure with a similar degree of supercoiling as found in the widespread left-handed coiled coils with heptad repeats. The basis for the right-handed geometry of VASP TD is a 15-residue repeat in its amino acid sequence, which reveals a characteristic pattern of hydrophobic residues. Hydrophobic interactions and a network of salt bridges render VASP TD highly thermostable with a melting point of 120 degrees C.
