Enables GTPase activator activity; phospholipase binding activity; and vinculin binding activity. Involved in activation of phospholipase C activity; cellular response to insulin stimulus; and cytoskeleton organization. Located in membrane raft. Colocalizes with actin filament; focal adhesion; and stress fiber. Human ortholog(s) of this gene implicated in colorectal cancer. Orthologous to human DLC1 (DLC1 Rho GTPase activating protein).
