Predicted to enable Glc3Man9GlcNAc2 oligosaccharide glucosidase activity. Predicted to be involved in protein N-linked glycosylation. Predicted to be located in endoplasmic reticulum. Predicted to be active in endoplasmic reticulum membrane. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation type IIb. Orthologous to human MOGS (mannosyl-oligosaccharide glucosidase). [provided by Alliance of Genome Resources, Apr 2022]
