Is predicted to encode a protein with the following domains: 3' exoribonuclease family, domain 1; PNPase/RNase PH domain superfamily; Ribosomal protein S5 domain 2-type fold; Tetratricopeptide-like helical domain superfamily; Exoribonuclease, phosphorolytic domain 1; Tetratricopeptide repeat; and Exoribonuclease, PH domain 2 superfamily. 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.
