General annotation (Comments)

Function

Catalyzes the initial step in the synthesis of dolichol-P-P-oligosaccharides.

Catalytic activity

UDP-N-acetyl-D-glucosamine + dolichyl phosphate = UMP + N-acetyl-D-glucosaminyl-diphosphodolichol.

Enzyme regulation

Enzyme activity is stimulated by phosphatidylglycerol and mannosylphosphoryldolichol and inhibited by tunicamycin.

Pathway

Protein modification; protein glycosylation.

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein.

Sequence similarities

Belongs to the glycosyltransferase 4 family.
