Predicted to enable GTPase activator activity and guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of cytokinesis, actomyosin contractile ring assembly. Predicted to be located in cytoplasm and nucleus. Is an ortholog of C. elegans ect-2. In C. elegans, ect-2 is involved in several processes, including asymmetric protein localization involved in cell fate determination; mitotic cytokinesis; and regulation of actin filament-based process.
