CYP27C1
CYP27C1 (cytochrome P450, family 27, subfamily C, polypeptide 1) is a protein that in humans is encoded by the CYP27C1 gene. The Enzyme Commission number (EC) for this protein is EC 1.14.19.53. The full accepted name is all-trans-retinol 3,4-desaturase and the EC number 1 classifies CYP27C1 as a oxidoreductase that acts on paired donor by reducing oxygen. It is also identifiable by the UniProt code Q4G0S4.
This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids.
The main function of the CYP27C1 enzyme is conversion of vitamin A1 (all-trans retinol) to vitamin A2 (all-trans 3,4-dehydroretinal).
