Protein Information (annotations from UniProt)

Database IDHIV0002473
UniProt IDQ6NUM9
Primary gene name(s)RETSAT
Synonym gene name(s)PPSIG
Protein nameAll-trans-retinol 13,14-reductase
Protein functionRetinol saturase carrying out the saturation of the 13-14 double bond of all-trans-retinol to produce all-trans-13,14-dihydroretinol. Has activity toward all-trans-retinol as substrate. Does not use all-trans-retinoic acid nor 9-cis, 11-cis or 13-cis-retinol isomers as substrates. May play a role in the metabolism of vitamin A, By similarity. {ECO:0000250}.
Subcellular locationEndoplasmic reticulum membrane {ECO:0000250};
Peripheral membrane protein {ECO:0000250}.
