Protein attributes

Sequence length	354 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Plays a key role in early steps of protein N-linked glycosylation by being required for the conversion of polyprenol into dolichol. Dolichols are required for the synthesis of dolichol-linked monosaccharides and the oligosaccharide precursor used for N-glycosylation. Acts as a polyprenol reductase that promotes the reduction of the alpha-isoprene unit of polyprenols into dolichols in a NADP-dependent mechanism By similarity.
Catalytic activity	Ditrans,polycis-dolichol + NADP+ = ditrans,polycis-polyprenol + NADPH.
Pathway	Protein modification; protein glycosylation.
Subcellular location	Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.
Sequence similarities	Belongs to the steroid 5-alpha reductase family. Polyprenol reductase subfamily.
