Target Background

Receptor for endothelin-1. Mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system. The rank order of binding affinities for ET-A is: ET1 > ET2 >> ET3.
Gene References into Functions
  1. Homocysteine up-regulates ETA receptor expression via the Sirt1/ERK1/2 signaling pathway in vascular smooth muscle cells. PMID: 28579512
  2. The results presented herein show that ETB receptors (R) have much weaker Ca(2+)-sensitizing effect than ETA-R and that ETB-R appear to be more dependent on Ca(2+) influx presumably through voltage-gated Ca(2+) channels (VGCC). PMID: 28757442
  3. endocytosis of ETA receptors following ligand binding preserves their active state by protection against antagonist. PMID: 28412414
