Is predicted to encode a protein with the following domains: Endoribonuclease Regnase 1/ ZC3H12 C-terminal domain; Rege-1, UBA-like domain; Ribonuclease Zc3h12a-like, NYN domain; Zc3h12a-like Ribonuclease NYN domain; UBA-like domain; and Endoribonuclease Regnase 1/ZC3H12, C-terminal domain. Is an ortholog of C. elegans rege-1.
