WASP is the protein that is defective in Wiskott-Aldrich syndrome (WAS). The majority of point mutations occur within the amino- terminal WH1 domain. The metabotropic glutamate receptors mGluR1alpha and mGluR5 bind a protein called homer, which is a WH1 domain homologue [2]. A subset of WH1 domains has been termed a "EVH1" domain [3] and appear to bind a polyproline motif.	Domain
