FAMILY	cytochrome P450 subfamily XIB
	multigenic cytochrome P450 superfamily of mixed-function monooxygenases

CATEGORY

enzyme , transport

basic FUNCTION	multifunctional enzyme with 18 hydroxylase, 18 hydroxysteroid dehydrogenase and accessorily 11 beta-hydroxylase activity, involved in mineralocorticoid biosynthesis
	preferentially catalyzing the conversion of 11- deoxycorticosterone to aldosterone via corticosterone and 18- hydroxycorticosterone

REGULATION

inhibited by

PRKCE

repressed by	NR5A1 ( its overexpression dramatically inhibited CYP11B2 expression and decreased aldosterone production) (Ye 2009)
		APEX1, a transcriptional repressor of CYP11B2 and differential APEX1 binding at -1651 of CYP11B2 results in altered gene expression

Other

regulated by calcium ion-signaling as well as cAMP-signaling
