Is predicted to encode a protein with the following domains: Glucosidase II beta subunit-like; Glucosidase 2 subunit beta; Glucosidase II beta subunit-like protein; Mannose-6-phosphate receptor binding domain superfamily; and Glucosidase 2 subunit beta-like. Is an ortholog of C. elegans ZK1307.8. In C. elegans, ZK1307.8 is involved in PERK-mediated unfolded protein response.
