Abstrakt: Squalene monooxygenase (SM) is a vital sterol synthesis enzyme across eukaryotic life. In yeast, it is a therapeutic target for treating certain fungal infections, and in mammals it is a rate-limiting enzyme that represents a key control point in the cholesterol synthesis pathway. SM introduces an oxygen atom to squalene, which becomes the signature oxygen of the hydroxyl group in cholesterol. Our knowledge of SM has advanced tremendously since its initial cloning and characterization. Early research developed mammalian SM inhibitors to target SM for cholesterol-lowering purposes. The substrate squalene has gained considerable interest for its health benefits and in nanomedicine for delivery of drugs. More recently, SM has been implicated as a key dysregulated component in certain cancers. In this review, we summarize our present knowledge of SM, focusing on the regulation of SM and the gene encoding it, SQLE. Furthermore, we offer insights into the role of SM across different organisms and its significance in human health and disease.
