Required for oocyte development and ovulation (PubMed:8707849, PubMed:12533508). Required for the translocation of secretory and transmembrane proteins into the endoplasmic reticulum in vitro (PubMed:8707849). Heterotrimeric complex composed of SEC61-alpha, SEC61-beta and SEC61-gamma. Expressed in the germline (PubMed:8707849). Expression in the germline is regulated in a sex- and meiotic cycle stage-specific manner (PubMed:8707849). Expressed in somatic tissues including the intestine and somatic gonad (PubMed:8707849). Expressed in the intestine more highly in hermaprodites than in males (PubMed:8707849). In hermaphrodites, weakly expressed in the spermatheca (PubMed:8707849). Belongs to the SecE/SEC61-gamma family.
