Protein Structure

UniProt Annotation

Function

Receptor for corticotropin (ACTH). This receptor is mediated by G proteins (G(s)) which activate adenylate cyclase (cAMP). {ECO:0000269PubMed:19329486, ECO:0000269PubMed:20371771}.

Subcellular Localization

Cell membrane; Multi-pass membrane protein.

Disease Associations

Glucocorticoid deficiency 1 (GCCD1) [MIM:202200]: A rare, potentially lethal, autosomal recessive disorder characterized by resistance to ACTH action on the adrenal cortex, adrenal insufficiency and an inability of the adrenal cortex to produce cortisol. It usually presents in the neonatal period or in early childhood with episodes of hypoglycemia and other symptoms related to cortisol deficiency, including failure to thrive, recurrent illnesses or infections, convulsions, and shock. In a small number of patients hypoglycemia can be sufficiently severe and persistent that it leads to serious long-term neurological damage or death. The diagnosis is readily confirmed with a low plasma cortisol measurement in the presence of an elevated ACTH level, and normal aldosterone and plasma renin measurements. {ECO:0000269PubMed:10971458, ECO:0000269PubMed:12213892, ECO:0000269PubMed:8094489, ECO:0000269PubMed:8227361, ECO:0000269PubMed:8636348}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

Melanocytes and corticoadrenal tissue.
