Comment typeDescription
Alternative ProductsEvent=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q9SI62-1; Sequence=Displayed; Name=2; IsoId=Q9SI62-2; Sequence=VSP_039793; Note=No experimental confirmation available.;
Catalytic ActivityDitrans,polycis-dolichol + NADP(+) = ditrans,polycis-polyprenol + NADPH.
FunctionPlays 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). {ECO:0000250}.
PathwayProtein modification; protein glycosylation.
SimilarityBelongs to the steroid 5-alpha reductase family. Polyprenol reductase subfamily. {ECO:0000305}.
Subcellular LocationEndoplasmic reticulum membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.
