Comments
Comment typeDescription
Catalytic ActivityCholesterol + AH(2) + O(2) = 25- hydroxycholesterol + A + H(2)O.
CofactorName=Fe cation; Xref=ChEBI
FunctionCatalyzes the formation of 25-hydroxycholesterol from cholesterol, leading to repress cholesterol biosynthetic enzymes. May play an important role in regulating lipid metabolism by synthesizing a corepressor that blocks sterol regulatory element binding protein (SREBP) processing. In testis, production of 25- hydroxycholesterol by macrophages may play a role in Leydig cell differentiation.
PtmN-glycosylated.
SimilarityBelongs to the sterol desaturase family.
Subcellular LocationEndoplasmic reticulum membrane {ECO
