Abstract
Following the discovery of endothelin (), functional characterization of the three endothelin (ET) isoforms (ET-1, ET-2 and ET-3) predicted that two mammalian receptor subtypes are present: the ETA receptor that is selective for ET-1, and the ETB receptor that has equal affinity for the three isoforms (). The existence of the two distinct high-affinity ET receptor subtypes has been confirmed by cloning. Unique cDNAs that code for ETA and ETB belonging to the G-protein linked heptahelical receptor superfamily are identified in human, bovine and rat tissues (, , , ). While pharmacological studies suggest that there may be more ET receptor subtypes (), no additional homologous mammalian cDNAs have been identified.
