Cytochrome P450 20A1 (CYP20A1)

CYP20A1 is a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases that catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein lacks one amino acid of the conserved heme binding site.

It also lacks the conserved I-helix motif AGX(D,E)T, suggesting that its substrate may carry its own oxygen.This RefSeq record was created from transcript and genomic sequence data because no single transcript was available for the full length of the gene. The extent of this transcript is supported by transcript alignments.
