Is predicted to encode a protein with the following domains: Exoribonuclease, PH domain 2 superfamily; Tetratricopeptide repeat; PNPase/RNase PH domain superfamily; Tetratricopeptide-like helical domain superfamily; 3' exoribonuclease family, domain 1; Exoribonuclease, phosphorolytic domain 1; and Ribosomal protein S5 domain 2-type fold. Is an ortholog of C. elegans
mat-3. In C. elegans,
mat-3 is involved in asymmetric cell division; polarity specification of anterior/posterior axis; and positive regulation of metaphase/anaphase transition of meiosis I.
