**Recombinant human CYP51A1 protein** is a key enzyme in sterol biosynthesis, primarily involved in cholesterol homeostasis. Belonging to the cytochrome P450 superfamily, CYP51A1 (sterol 14α-demethylase) catalyzes the oxidative removal of the 14α-methyl group from lanosterol, a critical step in converting lanosterol to cholesterol in humans. This endoplasmic reticulum-membrane-anchored enzyme is expressed in various tissues, with high activity in the liver, adrenal glands, and gonads. Its fungal homolog (CYP51) is a target for azole antifungals, but human CYP51A1’s structural divergence limits drug cross-reactivity, reducing host toxicity.
Recombinant CYP51A1 is produced using heterologous expression systems (e.g., *E. coli*, yeast, or mammalian cells*) to study its catalytic mechanisms, substrate interactions, and inhibition. Purified recombinant protein enables high-throughput screening of inhibitors for antifungal or cholesterol-lowering drug development. Mutations in *CYP51A1* are linked to metabolic disorders, making this protein a focus for understanding genetic defects and cholesterol-related pathologies. Research also explores its role in cancer and neurodegenerative diseases due to cholesterol’s vital role in cell membranes and signaling. Its recombinant form provides a controlled tool for structural biology (e.g., X-ray crystallography) and mechanistic enzymology studies.
