EVH1 Domain
Class:Pro-rich binding

Domain binding and function:
The EVH1 domain is a protein module of ~115 amino acids found in a number of scaffolding proteins that mediate the assembly of multiprotein complexes involved in control of the actin cytoskeleton or in signal transduction in postsynaptic compartments. This domain was originally identified at the N-terminus of the Drosophila protein Enabled (Ena), its mammalian counterpart (Mena) and the closely related protein Vasp (hence the term Ena/Vasp Homology domain 1). EVH1 domains are also found in an additional member of the Mena family, Evl, in the WASP docking protein that is affected by mutations that cause the immunodeficiency Wiskott-Aldrich syndrome, and in the Homer family of synaptic proteins that interact with group 1 metabotropic glutamate receptors. EVH1 domains can be divided into two classes based on their proline-rich ligands. The class I EVH1 domains including the Ena/Vasp proteins recognize a FPxΦP motif, whereas the class II family of postsynaptic receptor-associated proteins recognize PPxxF motifs. These motifs are commonly found in components of the cytoskeleton, such as Vinculin and Zyxin, as well as in the ActA protein of the pathogenic bacterium Listeria monocytogenes, which regulates bacterial motility by controling actin polymerization in the infected cell.
