CC -!- FUNCTION: Plays a key role in early steps of protein N-linked
CC glycosylation by being required for the conversion of polyprenol into
CC dolichol. Dolichols are required for the synthesis of dolichol-linked
CC monosaccharides and the oligosaccharide precursor used for N-
CC glycosylation. Acts as a polyprenol reductase that promotes the
CC reduction of the alpha-isoprene unit of polyprenols into dolichols in a
CC NADP-dependent mechanism. {ECO:0000256|RuleBase:RU367081}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=di-trans,poly-cis-dolichol + NADP(+) = di-trans,cis-polyprenol
CC + H(+) + NADPH; Xref=Rhea:RHEA:34279, Rhea:RHEA-COMP:9521, Rhea:RHEA-
CC COMP:9525, ChEBI:CHEBI:15378, ChEBI:CHEBI:16091, ChEBI:CHEBI:57783,
CC ChEBI:CHEBI:58349, ChEBI:CHEBI:67132; EC=1.3.1.94;
CC Evidence={ECO:0000256|ARBA:ARBA00000394,
CC ECO:0000256|RuleBase:RU367081};
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC {ECO:0000256|ARBA:ARBA00004922, ECO:0000256|RuleBase:RU367081}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000256|RuleBase:RU367081}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the steroid 5-alpha reductase family. Polyprenol
CC reductase subfamily. {ECO:0000256|RuleBase:RU367081}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|RuleBase:RU367081}.
