What is the official name of the CYP11B2 gene?
The official name of this gene is “cytochrome P450, family 11, subfamily B, polypeptide 2.”
CYP11B2 is the gene's official symbol. The CYP11B2 gene is also known by other names, listed below.

What is the normal function of the CYP11B2 gene?
The CYP11B2 gene provides instructions for making an enzyme called aldosterone synthase (previously known as corticosterone methyloxidase). This enzyme is found in the adrenal glands, which are located on top of the kidneys. Aldosterone synthase is a member of the cytochrome P450 family of enzymes. These enzymes are involved in the formation and breakdown of various molecules within cells.
Aldosterone synthase helps produce a hormone called aldosterone. Aldosterone helps control blood pressure by maintaining proper salt and fluid levels in the body. The aldosterone synthase enzyme is involved in a series of three chemical reactions that produce aldosterone from other (precursor) molecules: the conversion of 11-deoxycorticosterone to corticosterone, the conversion of corticosterone to 18-hydroxycorticosterone, and the conversion of 18-hydroxycorticosterone to aldosterone.
Does the CYP11B2 gene share characteristics with other genes?
The CYP11B2 gene belongs to a family of genes called CYP (cytochrome P450s).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
