SCUBA

DHCR7 — 7-dehydrocholesterol reductase

DHCR7 belongs to a gene co-expression module in 2 of 28 SCUBA cell types. Each module groups genes that rise and fall together in that cell type; the genes it shares a module with are its closest co-expression partners there.

Function

Oxidoreductase that catalyzes the last step of the cholesterol synthesis pathway, which transforms cholesta-5,7-dien- 3beta-ol (7-dehydrocholesterol,7-DHC) into cholesterol by reducing the C7-C8 double bond of its sterol core. Can also metabolize cholesta-5,7,24-trien-3beta-ol (7-dehydrodemosterol, 7-DHD) to desmosterol, which is then metabolized by the Delta(24)-sterol reductase (DHCR24) to cholesterol (By similarity). Modulates ferroptosis (a form of regulated cell death driven by iron-dependent lipid peroxidation) through the metabolic breakdown of the anti- ferroptotic metabolites 7-DHC and 7-DHD which, when accumulated, divert the propagation of peroxyl radical-mediated damage from phospholipid components to its sterol core, protecting plasma and mitochondrial membranes from phospholipid autoxidation. Component of the microsomal antiestrogen binding site (AEBS), a multiproteic complex at the ER membrane that consists of an association between cholestenol Delta-isomerase/EBP and DHCR7. This complex is responsible for cholesterol-5,6-epoxide hydrolase (ChEH) activity, which consists in the hydration of cholesterol-5,6-epoxides (5,6-EC) into cholestane- 3beta,5alpha,6beta-triol (CT). The precise role of each component of this complex has not been described yet.
