Is predicted to encode a protein with the following domains: Anaphase-promoting complex, cyclosome, subunit 3; Tetratricopeptide-like helical domain superfamily; and Tetratricopeptide repeat. Is an ortholog of C. elegans
mat-1. In C. elegans,
mat-1 is involved in asymmetric cell division; cortical granule exocytosis; and polarity specification of anterior/posterior axis.
