It is a cell cycle regulator that plays key roles in cytokinesis [1]. ECT2 contains triple copies of the BRCT domain (BRCT0, BRCT1 (Pfam:PF12738) and BRCT2 (Pfam:PF00533) at the N-terminal, separated from the C-terminal DH (Pfam:PF00621) and PH domains by a linker of about 100 residues. This entry represents the PH domain [1]. The BRCT and DH-PH domains mediate intra-molecular interactions that restrains ETC2 activity during interphase.
