Is predicted to encode a protein with the following domains: PNPase/RNase PH domain superfamily; Exoribonuclease, phosphorolytic domain 1; 3' exoribonuclease family, domain 1; Ribosomal protein S5 domain 2-type fold; and Exoribonuclease, PH domain 2 superfamily. Is an ortholog of C. elegans
crn-5. In C. elegans,
crn-5 is involved in RNA processing and apoptotic DNA fragmentation.
