A human BK-2 bradykinin receptor was cloned from the lung fibroblast cell line CCD-16Lu. The cDNA clone encodes a 364 amino acid protein that has the characteristics of a seven transmembrane domain G-protein coupled receptor. The predicted amino acid sequence of the human BK-2 receptor is 81% identical to the smooth muscle rat BK-2 receptor (1).(More)
A cDNA clone encoding a human B1 bradykinin receptor was isolated from a human embryonic lung fibroblast cDNA library by expression cloning. The photoprotein aequorin was utilized as an indicator of the ability of the B1 receptor agonist [des-Arg10]kallidin to mediate Ca2+ mobilization in Xenopus laevis oocytes injected with RNA. A clone was isolated with a(More)
Bradykinin has been implicated in nociception and inflammation. To examine the relative significance of B1 and B2 bradykinin receptor subtypes in sympathetic and sensory ganglia, the electrophysiological effects of bradykinin analogues and the expression of receptor subtype mRNA were examined in wild-type and "B2 knockout" mice from which the B2 receptor(More)
The pharmacology of cloned B2 bradykinin receptors heterologously expressed in cell lines lacking any endogenous bradykinin receptors was analyzed. The possibility of B2 bradykinin receptor heterogeneity had been proposed on the basis of numerous studies in various tissue preparations. The results reported here permit a direct evaluation of some of these(More)
A genomic clone encoding the mouse B1 receptor was isolated by homology to the human B1 receptor cDNA. The deduced amino acid sequence of the mouse B1 receptor is 72% identical to the human B1 receptor and 73% identical to the rabbit B1 receptor. Ligand binding studies of the mouse B1 receptor expressed in COS cells indicate that it has the pharmacological(More)
Mice that are homozygous for the targeted disruption of the gene encoding the B2 bradykinin receptor have been generated. The gene disruption results in a deletion of the entire coding sequence for the B2 receptor. The disruption of the B2 receptor gene has been confirmed by genetic, biochemical, and pharmacological analyses. Mice that are homozygous for(More)
Two mammalian genes encoding bradykinin (BK) receptors termed B1 and B2 have been identified by molecular cloning techniques. Some pharmacological data suggest the existence of further subtypes of the B2 receptor. To unambiguously determine whether additional genes encoding B2 BK receptors might exist in mammals, steps have been taken toward the generation(More)
The contributions of B1 and B2 bradykinin receptors to acute and chronic inflammatory hyperalgesia were examined using the peptide B1 receptor antagonist des-Arg9[Leu8]bradykinin and transgenic Bk2r-/- mice. In normal rats and mice, des-Arg9[Leu8]bradykinin (30 nmol/kg i.v. or s.c.) inhibited carrageenan-induced hyperalgesia and the late phase nociceptive(More)
A rigorous analysis of the Merck-sponsored EST data with respect to known gene sequences increases the utility of the data set and helps refine methods for building a gene index. A highly curated human transcript data base was used as a reference data set of known genes. A detailed analysis of EST sequences derived from known genes was performed to assess(More)
MOTIVATION To make effective use of the vast amounts of expressed sequence tag (EST) sequence data generated by the Merck-sponsored EST project and other similar efforts, sequences must be organized into gene classes, and scientists must be able to 'mine' the gene class data in the context of related genomic data. RESULTS This paper presents the Merck(More)
