Transcription activator (By similarity). May activate expression of the pro-apoptotic genes ced-4 and ced-3 (PubMed:17881492). Required for constitutive, and for DNA damage-induced, programmed cell death of germ cells (PubMed:17881492). Reduced level of constitutive germ cell apoptosis on a ced-6 mutant background, in hermaphrodites (PubMed:17881492). Blocks DNA damage-induced germ cell apoptosis, but does not affect associated cell-cycle arrest (PubMed:17881492). Belongs to the E2F/DP family. Extended N-terminus.
