Predicted to enable alpha-1,3-mannosyltransferase activity and dolichyl pyrophosphate Glc1Man9GlcNAc2 alpha-1,3-glucosyltransferase activity. Predicted to be involved in oligosaccharide-lipid intermediate biosynthetic process and protein N-linked glycosylation via asparagine. Predicted to be integral component of membrane. Predicted to be active in endoplasmic reticulum membrane. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation Ih and polycystic liver disease. Orthologous to human ALG8 (ALG8 alpha-1,3-glucosyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
