Is predicted to encode a protein with the following domains: Ras GTPase-activating domain; PH-like domain superfamily; Rho GTPase activation protein; Ras GTPase-activating protein; Pleckstrin homology domain; PH domain; and GTPase-activator protein for Ras-like GTPase. Is an ortholog of C. elegans gap-1. In C. elegans, gap-1 is involved in chemosensory behavior; learning or memory; and negative regulation of Ras protein signal transduction.
