Is predicted to encode a protein with the following domains: PD-(D/E)XK endonuclease-like domain, AddAB-type; PD-(D/E)XK endonuclease-like domain superfamily; and PD-(D/E)XK nuclease superfamily. Is an ortholog of C. elegans C27H6.9 and
tofu-1. In C. elegans,
tofu-1 is involved in primary piRNA processing.
