CYP46A1 [ENSP00000261835]
 
cytochrome P450, family 46, subfamily A, polypeptide 1; Involved in the turnover of cholesterol. It converts cholesterol into 24S-hydroxycholesterol and, to a lesser extent, 25-hydroxycholesterol
CYP27A1 [ENSP00000258415]
 
cytochrome P450, family 27, subfamily A, polypeptide 1; Catalyzes the first step in the oxidation of the side chain of sterol intermediates; the 27-hydroxylation of 5-beta- cholestane-3-alpha,7-alpha,12-alpha-triol. Has also a vitamin D3- 25-hydroxylase activity
