General annotation (Comments)

Function	This transmembrane glycoprotein is involved in the control of cholesterol biosynthesis. It is the rate-limiting enzyme of the 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.
Sequence similarities	Belongs to the HMG-CoA reductase family.
