Subcellular location

Subcellular Location:
Microsome membrane; Multi-pass membrane protein. Endoplasmic reticulum membrane; Multi-pass membrane protein.

Function

Function:
Catalyzes the first oxygenation step in sterol biosynthesis and is suggested to be one of the rate-limiting enzymes in this pathway.
Pathway:
Terpene metabolism; lanosterol biosynthesis; lanosterol from farnesyl diphosphate: step 2/3.
Catalytic Activity:
Squalene + + O(2) = (3S)-2,3-epoxy-2,3-dihydrosqualene + + H(2)O.
Cofactor:
