Agonist Comments
In mammals, the endothelin (ET) family comprises three endogenous isoforms, ET-1, ET-2 and ET-3. ET-1 is the principal isoform in the human cardiovascular system and is one of the most ubiquitous, potent and unusually long lasting constrictor of human vessels. ET-2 has been less extensively studied than other ET peptides but the peptide is present in human cardiovascular tissues and ET-2 was as potent a vasoconstrictor as ET-1 in human arteries and veins. VIC (vasoactive intestinal contractor) is the murine isoform of ET-2. Endothelial cells do not synthesise ET-3 but the mature peptide is detectable in plasma and other tissues including heart and brain. ET-3 is unique in that it is the only endogenous isoform that distinguishes between the two endothelin receptors. It has the same affinity at the ETB receptor as ET-1 but, at physiological concentrations, has little or no affinity for the ETA.The only endogenous peptides with a high degree of sequence similarity to the ETs are the sarafotoxins (S6a, S6b, S6c, S6d). This family of 21aa peptides were originally discovered in the venom of a snake, Atractaspis engadensis [11].
ETA receptors are initially classfied according to the the rank order of potency of ET agonists with ET-1 being equipotent to ET-2 but ET-3 typically displaying 100 fold less potency and confirmed by using selective peptide antagonists (eg BQ123 and FR139317) or non-peptide antagonists (eg PD156707 or A127742).

Antagonist Comments
Antagonists are currently classified as either ETA-selective, ETB-selective or mixed antagonists that display similar affinity for both receptors. The most highly selective peptide antagonists (4-5 orders of selectivity) for the ETA receptors are the cyclic pentapeptide, BQ123 and the modified linear peptide FR139317. Unlike peptide antagonists, many non-peptide ETA receptor-selective antagonists have oral bioavalibility and some may cross the blood brain barrier. [3,10-12,23,50].

Primary Transduction Mechanisms
Transducer Effector/Response
Gq/G11 family Phospholipase C stimulation
Phospholipase A2 stimulation
Phospholipase D stimulation
Comments:  Activation of ETA receptors to produce a range of biological actions in different tissues is thought to be mediated by a number of transduction systems coupled to various types of G-protein, predominatly Gq/11 but there is also evidence for Gi/o (lactotrophs, myocytes), Gi2 and Gs. The major enzyme systems activated include phospholipase C, A2 and D. Calcium signalling is a nearly universal response for ET-1 induced vasoconstriction via generation of IP3 and DAG whereas cyclic nucleotide levels often remain unaltered. ET-1 also has mitogenic actions leading to cell proliferation [21,44,48-49]

Tissue Distribution
ETA receptors are mainly localised to vascular smooth muscle cells (where they are the predominant sub-type) and therefore in all tissues receiving a blood supply including heart, lung and brain. ETA receptors are also present on other cell types including myocytes within the heart.

Physiological Consequences of Altering Gene Expression
Mice deficient for ETA receptor, mimic the human conditions collectively termed CATCH 22 or velocardiofacial syndrome, which includes severe craniofacial deformities and defects in the cardiovascular outflow tract. Great vessel malformations highly similar to those seen in neural crest-ablated chick embryos and human congenital cardiac defect also occur.

Biologically Significant Variants
A gene encoding a truncated (109 amino acids deleted) ETA receptor was more abundant than the wild type in melanoma cell lines and tissue. The expressed receptor did not bind ET-1, suggesting reduced responsiveness to ET-1 in these tumours.
Type:  Splice variants.
Species:  Human
References:  55
General Comments
Antagonists that block both ETA and ETB receptors (also called mixed or balanced) include peptides such as TAK044. Non-peptide compounds included bosentan (RO470203, Tracleer [7]) the first antagonist in clinical use [13] SB209670 [22], SB217242 (enrasentan, [39]) and RO610612 (tezosentan, [8]). The distinction between antagonists that are ETA selective and those that block both ETAand ETB receptors is not precise but generally the former display greater than 100-fold selectivity for the ETAsubtype and the latter less than 100-fold.

For reviews on endothelin receptors see [4,18,47].
