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

  2. miR200c regulates the proliferation, apoptosis and invasion of gastric carcinoma cells through the downregulation of EDNRA expression. PMID: 29286062
  3. Presence of SST5, CXCR4 and ETA on tumor cells and of SST3, CXCR4 and ETA on microvessels gradually increased from grade II to grade IV tumors. PMID: 29696364
  4. There is no association between the C+70G polymorphism of the EDNRA gene and the development of ischemic atherothrombotic stroke. PMID: 29064794
  5. endothelin-A receptor-activated ABCB1 expression has a role in nintedanib resistance in FGFR1-driven small cell lung cancer PMID: 27367030
  6. Endothelin-1 possesses an anti-apoptotic effect in vascular endothelial cells and this effect is mediated, to a great extent, via the activation of EDNRB, with a minor contribution via activation of EDNRA. PMID: 28732172
  7. ETA and ETB receptors are present in human haemorrhoids with ETB receptors predominating PMID: 28095606
  8. ETAR stimulation acted via downstream G-protein Galphaq/11 and Rho GTPase to suppress the Hippo pathway, thus leading to YAP/TAZ activation, which was required for ETAR-induced tumorigenesis. Overall, these results indicate a critical role of the YAP/TAZ axis in ETAR signaling PMID: 28249901
  9. Data show that endothelin A receptor drives invadopodia function by direct interaction of beta-arrestin-1 (beta-arr1) with Rho guanine nucleotide exchange factor (GEF) 11 protein (PDZ-RhoGEF). PMID: 26522724

  11. Data suggest that TNFalpha (tumor necrosis factor-alpha) induces proliferation of airway smooth muscle cells via ET1 (endothelin-1), GM-CSF (granulocyte-macrophage colony-stimulating factor), and IL6 (interleukin 6) signaling; ET1 induces cell proliferation via ETAR (endothelin receptor type A); ETBR (endothelin receptor type B) is up-regulated by TNFalpha and appears to mediate ET1 effects on cell proliferation.

  13. Data show that auriculo-condylar syndrome (ACS)-associated mutations in G protein subunit alpha i3 (GNAI3) produce dominant-negative Galpha(i3) mutant proteins that couple to endothelin type A receptor (ET(A)R). PMID: 27072656

  15. High ETAR expression is associated with ovarian carcinoma. PMID: 26675258
  16. Data show that macitentan interferes with the profibrotic action of transforming growth factor-beta (TGF-beta), blocking the endothelin receptor type A (ET-1 receptor) portion of the ET-1/TGF-beta receptor complex. PMID: 26357964
