Cytochrome P450 family 51 subfamily A member 1 (CYP51A1)

Target
CYP51A1
Molecular classification
Enzyme, Cytochrome P450, Monooxygenase
01

Overview

CYP51A1 is a monooxygenase enzyme belonging to the cytochrome P450 superfamily. It catalyzes the 14α-demethylation of lanosterol, a crucial step in the biosynthesis of cholesterol in animals, ergosterol in fungi, and other sterols in plants. This enzyme is highly conserved across eukaryotes and is a major target for antifungal drugs (azole antifungals) that disrupt ergosterol production in fungi. In humans, mutations or dysregulation can impact cholesterol synthesis, and it has been explored as a target for herbicides and cholesterol-lowering agents.
