CC -!- FUNCTION: Adds the second 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 Glc(1)Man(9)GlcNAc(2)-PP-Dol (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a dolichyl beta-D-glucosyl phosphate + alpha-D-Glc-(1->3)-
CC alpha-D-Man-(1->2)-alpha-D-Man-(1->2)-alpha-D-Man-(1->3)-[alpha-D-

CC ChEBI:CHEBI:132522; EC=2.4.1.265;
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC Multi-pass membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the ALG6/ALG8 glucosyltransferase family.
CC {ECO:0000305}.
