Predicted to enable several functions, including GBD domain binding activity; GTP binding activity; and profilin binding activity. Involved in cellular response to insulin stimulus; cortical actin cytoskeleton organization; and negative regulation of protein localization to plasma membrane. Acts upstream of or within regulation of cell shape. Located in membrane raft. Is expressed in telencephalon. Orthologous to human RHOQ (ras homolog family member Q).
