CC -!- FUNCTION: Catalyzes the initial step of dolichol-linked oligosaccharide
CC biosynthesis in N-linked protein glycosylation pathway: transfers
CC GlcNAc-1-P from UDP-GlcNAc onto the carrier lipid dolichyl phosphate
CC (P-dolichol), yielding GlcNAc-P-P-dolichol.
CC {ECO:0000256|ARBA:ARBA00003598}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a dolichyl phosphate + UDP-N-acetyl-alpha-D-glucosamine = N-
CC acetyl-alpha-D-glucosaminyl-diphosphodolichol + UMP;
CC Xref=Rhea:RHEA:13289, Rhea:RHEA-COMP:9517, Rhea:RHEA-COMP:9519,
CC ChEBI:CHEBI:57683, ChEBI:CHEBI:57705, ChEBI:CHEBI:57865,

CC Evidence={ECO:0000256|ARBA:ARBA00034004};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|ARBA:ARBA00001946};
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC {ECO:0000256|ARBA:ARBA00004922}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000256|ARBA:ARBA00004477}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004477}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 4 family.
CC {ECO:0000256|ARBA:ARBA00009317}.
