Summary: Enables corticosterone 18-monooxygenase activity and steroid 11-beta-monooxygenase activity. Involved in several processes, including cellular response to mechanical stimulus; cellular response to potassium ion starvation; and steroid hormone biosynthetic process. Located in dendrite. Used to study heart disease; hypertension; and myocardial infarction. Biomarker of congestive heart failure; hypertension; myocarditis; and renal tubular acidosis. Human ortholog(s) of this gene implicated in congenital adrenal hyperplasia; glucocorticoid-remediable aldosteronism; and primary hyperaldosteronism. Orthologous to human CYP11B1 (cytochrome P450 family 11 subfamily B member 1). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
