Abstract

By screening a cDNA library derived from the A10 rat vascular smooth muscle cell line for functional expression in COS cells, we have isolated a high-affinity receptor for endothelin 1 (Kd = 476 pM) and endothelin 2. The affinity of the cloned endothelin receptor for endothelin 3 is greater than 100 times less in A10 cells and in a CHO cell line stably transformed by the endothelin receptor cDNA. The 426-amino acid receptor polypeptide has seven putative hydrophobic transmembrane domains and is presumed to be a member of the family of guanine nucleotide-binding regulatory (G) protein-coupled receptors. Microinjection of in vitro transcripts of the cloned cDNA into CHO cells confers a transient increase in intracellular calcium in response to endothelin 1, indicating that the receptor is functional and couples to the appropriate G protein(s). RNA analysis reveals high expression in rat lung and heart, tissues known to exhibit binding to iodinated endothelin 1.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
