General annotation (Comments)

Function

This transmembrane glycoprotein is involved in the control of cholesterol biosynthesis. It is the rate-limiting enzyme of sterol biosynthesis.

Catalytic activity

(R)-mevalonate + CoA + 2 NADP+ = (S)-3-hydroxy-3-methylglutaryl-CoA + 2 NADPH.

Pathway

Metabolic intermediate biosynthesis; (R)-mevalonate biosynthesis; (R)-mevalonate from acetyl-CoA: step 3/3.

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein.

Induction

By estrogen; in male liver.

Sequence similarities

Belongs to the HMG-CoA reductase family.
