Predicted to enable deoxyribonuclease inhibitor activity; protein domain specific binding activity; and protein folding chaperone. Acts upstream of or within negative regulation of apoptotic DNA fragmentation; positive regulation of apoptotic process; and thymocyte apoptotic process. Predicted to be located in several cellular components, including chromatin; cytosol; and nucleus. Predicted to be part of protein-containing complex. Is expressed in several structures, including brain; heart; hemolymphoid system gland; liver; and metanephros. Orthologous to human DFFA (DNA fragmentation factor subunit alpha).
