CC -!- FUNCTION: Adds the first glucose residue to the lipid-linked
CC oligosaccharide precursor for N-linked glycosylation. Transfers glucose
CC from dolichyl phosphate glucose (Dol-P-Glc) onto the lipid-linked
CC oligosaccharide Man(9)GlcNAc(2)-PP-Dol (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a dolichyl beta-D-glucosyl phosphate + alpha-D-Man-(1->2)-
CC alpha-D-Man-(1->2)-alpha-D-Man-(1->3)-[alpha-D-Man-(1->2)-alpha-D-

CC ChEBI:CHEBI:132520, ChEBI:CHEBI:132521; EC=2.4.1.267;
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000305};
CC Multi-pass membrane protein {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the ALG6/ALG8 glucosyltransferase family.
CC {ECO:0000305}.
