This gene encodes the receptor for endothelin-1, a peptide that plays a role in potent and long-lasting vasoconstriction. This receptor associates with guanine-nucleotide-binding (G) proteins, and this coupling activates a phosphatidylinositol-calcium second messenger system. Polymorphisms in this gene have been linked to migraine headache resistance. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]
Forensic Context
A study in humans demonstrated that the EDNRA is highly expressed in pericytes of the corpus cavernosum and its expression is downregulated in patients with erectile dysfunction [Zhao et al. DOI:10.1038/s41467-022-31950-9]. In rats, a study of liver gene expression following burn injury found that the EDNRA was significantly altered in expression on day 7 post-injury [Jayaraman et al. DOI:10.1016/j.jss.2007.05.025].
