Summaries for CYP11B1 Gene

Entrez Gene Summary for CYP11B1 Gene

  • This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the mitochondrial inner membrane and is involved in the conversion of progesterone to cortisol in the adrenal cortex. Mutations in this gene cause congenital adrenal hyperplasia due to 11-beta-hydroxylase deficiency. Transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for CYP11B1 Gene

CYP11B1 (Cytochrome P450, Family 11, Subfamily B, Polypeptide 1) is a Protein Coding gene. Diseases associated with CYP11B1 include adrenal hyperplasia, congenital, due to 11-beta-hydroxylase deficiency and aldosteronism, glucocorticoid-remediable. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include electron carrier activity and heme binding. An important paralog of this gene is CYP11A1.

UniProtKB/Swiss-Prot for CYP11B1 Gene

  • Has steroid 11-beta-hydroxylase activity. In addition to this activity, the 18 or 19-hydroxylation of steroids and the aromatization of androstendione to estrone have also been ascribed to cytochrome P450 XIB

Tocris Summary for CYP11B1 Gene

  • Cytochrome P450 (CYP450) enzymes are a diverse group of catalysts that contains 57 members in humans. CYPs are usually membrane-bound and are localized to the inner mitochondrial or endoplasmic reticular membrane. CYPs have oxygenase activity and commonly catalyze redox reactions, involving the oxidation of the substrate and reduction of water. This group of enzymes contain a heme ion within the active site, which is essential for catalytic activity. CYPs have been found in all organisms tested and are ubiquitously expressed. They are found at high levels in the liver, where they have an important role in metabolism of drugs and endogenous toxic compounds (for example bilirubin). Most CYPs can metabolize numerous substrates and this accounts for their major role in drug interactions. CYPs also have functions in steroid hormone synthesis, cholesterol synthesis and vitamin D metabolism.

Disorders for CYP11B1 Gene

(2) OMIM Diseases for CYP11B1 Gene (610613)


  • Adrenal hyperplasia 4 (AH4) [MIM:202010]: A form of congenital adrenal hyperplasia, a common recessive disease due to defective synthesis of cortisol. Congenital adrenal hyperplasia is characterized by androgen excess leading to ambiguous genitalia in affected females, rapid somatic growth during childhood in both sexes with premature closure of the epiphyses and short adult stature. Four clinical types: salt wasting (SW, the most severe type), simple virilizing (SV, less severely affected patients), with normal aldosterone biosynthesis, non-classic form or late-onset (NC or LOAH)and cryptic (asymptomatic). {ECO:0000269 PubMed:16046588, ECO:0000269 PubMed:2022736, ECO:0000269 PubMed:20331679, ECO:0000269 PubMed:20947076, ECO:0000269 PubMed:9302260}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Familial hyperaldosteronism 1 (FH1) [MIM:103900]: A disorder characterized by hypertension, variable hyperaldosteronism, and abnormal adrenal steroid production, including 18-oxocortisol and 18-hydroxycortisol. There is significant phenotypic heterogeneity, and some individuals never develop hypertension. Note=The disease is caused by mutations affecting the gene represented in this entry. The molecular defect causing hyperaldosteronism familial 1 is an anti-Lepore-type fusion of the CYP11B1 and CYP11B2 genes. The hybrid gene has the promoting part of CYP11B1, ACTH-sensitive, and the coding part of CYP11B2.
