7-Dehydrocholesterol Reductase

**Semantic type:** Amino Acid, Peptide, or Protein|Enzyme

**Definition:** 7-dehydrocholesterol reductase (475 aa, ~54 kDa) is encoded by the human DHCR7 gene. This protein is involved in reducing the C7-C8 double bonds in cholesta-5,7-dien-3beta-ol (7-dehydrocholesterol/7-DHC) and cholesta-5,7,24-trien-3beta-ol during cholesterol biosynthesis.
