Key enzyme in the cholesterol biosynthesis pathway. Catalyzes the cyclization of (S)-2,3 oxidosqualene to lanosterol, a reaction that forms the sterol nucleus ( ). Through the production of lanosterol may regulate lens protein aggregation and increase transparency .
Subcellular locations: Endoplasmic reticulum membrane
