General annotation (Comments)
| Function | 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. |
| Subunit structure | Interacts with HDAC7 and KAT5. Ref.17 |
| Subcellular location | |
| Tissue specificity | Isoform 1, isoform 3 and isoform 4 are expressed in a variety of tissues, with highest levels in the aorta and cerebellum, followed by lung, atrium and cerebral cortex, lower levels in the placenta, kidney, adrenal gland, duodenum, colon, ventricle and liver but no expression in umbilical vein endothelial cells. Within the placenta, isoform 1, isoform 2, isoform 3 and isoform 4 are expressed in the villi and stem villi vessels. Ref.8 Ref.16 |
| Sequence similarities | Belongs to the G-protein coupled receptor 1 family. Endothelin receptor subfamily. EDNRA sub-subfamily. |

| Isoform 2 (identifier: P25101-2) Also known as: Delta-3; The sequence of this isoform differs from the canonical sequence as follows: 141-161: LLAGRWPFDHNDFGVFLCKLF → VQSSCLLESCSGNWDSFGNCH 162-427: Missing. | ||||||
| Isoform 3 (identifier: P25101-3) Also known as: Delta-4; The sequence of this isoform differs from the canonical sequence as follows: 183-187: RYRAV → SSTKM 188-427: Missing. | ||||||
| Isoform 4 (identifier: P25101-4) Also known as: Delta-3,4; The sequence of this isoform differs from the canonical sequence as follows: 141-249: Missing. | ||||||
| Isoform 5 (identifier: P25101-5) The sequence of this isoform differs from the canonical sequence as follows: 1-225: Missing. | ||||||
| Note: No experimental confirmation available. |
