Caenorhabditis elegans

CRN-2

CELE_CD4.2, CD4.2
crn-2 encodes a cell death-related nuclease, homologous to the magnesium-dependant TatD nuclease of E. coli; CRN-2 is required for normal levels of DNA degradation during apoptosis; crn-2(RNAi) 1.5-fold stage embryos display TUNEL labelling of nuclei that is five-fold higher than that seen in untreated N2 animals; CRN-2 promotes both DNA degradation and cell corpse engulfment, in a partially redundant pathway that includes CRN-3 but is parallel to CPS-6; CRN-2 is predicted to be mitochondrial.
