Abstract: The present invention is a cloned human BK-2 bradykinin receptor cloned from a human lung fibroblast cell line. A cDNA clone, also part of the instant invention, encodes a novel 364 amino acid protein (the BK-2 receptor) that has the characteristics of a seven transmembrane domain G-protein coupled receptor. The invention is used to express a BK-2 bradykinin receptor in a host mammalian cell to screen for pharmaceutical antagonists or agonists which bind to or interact with the BK-2 bradykinin receptor protein.

Abstract: A recombinant human neurokinin-3 receptor (hereinafter identified as human NK3R) is disclosed which has been prepared by polymerase chain reaction techniques.
