Predicted to enable GTPase regulator activity; protein homodimerization activity; and small GTPase binding activity. Predicted to be involved in several processes, including activation of GTPase activity; bicellular tight junction assembly; and regulation of cell cycle process. Predicted to act upstream of or within cell morphogenesis. Predicted to be located in several cellular components, including bicellular tight junction; cleavage furrow; and midbody. Predicted to be part of centralspindlin complex. Predicted to be active in cell cortex and nucleus. Orthologous to human ECT2 (epithelial cell transforming 2).
