Summaries for CYP20A1 Gene

Entrez Gene Summary for CYP20A1 Gene

  • This gene encodes 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.

GeneCards Summary for CYP20A1 Gene

CYP20A1 (Cytochrome P450 Family 20 Subfamily A Member 1) is a Protein Coding gene. Diseases associated with CYP20A1 include Bronchus Cancer. Among its related pathways are cytochrome P450 and Phase II conjugation. GO annotations related to this gene include iron ion binding and oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen.
