Is predicted to encode a protein with the following domains: Fes/CIP4, and EFC/F-BAR homology domain; AH/BAR domain superfamily; SH3-like domain superfamily; SH3 domain; and FCH domain. Is an ortholog of C. elegans toca-1. In C. elegans, toca-1 is involved in several processes, including negative regulation of protein localization to adherens junction; positive regulation of egg-laying behavior; and regulation of cellular component organization.
