Abstract

DNA encoding an endothelin receptor shown in SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, or SEQ ID NO: 4. In the Sequence Listing is isolated from cDNA which is prepared from poly(A).sup.+ RNA derived from a human placenta. In addition, an expression vector containing the DNA and a transformant containing the expression vector are obtained. An endothelin receptor is obtained by culturing this transformant. A receptor shown in SEQ ID NO: 1 and SEQ ID NO: 2 is an ET.sub.A -receptor which has a high affinity for endothelins 1 and 2, especially for the endothelin 1. A receptor shown in SEQ ID NO: 3 and SEQ ID NO: 4 is an ET.sub.B -receptor which has an affinity for endothelins 1, 2 and 3 with no selectivity.
