A prototypic study of the molecular mechanisms of activation or inactivation of peptide hormone G protein-coupled receptors was carried out on the human B2 bradykinin receptor. A detailed… (More)
A preliminary model of the rat AT1A angiotensin II (AII) receptor (Joseph, M. P., Maigret, B., Bonnafous J.-C., Marie, J., and Scheraga, H. A. (1995) J. Protein Chem. 14, 381-398) has predicted an… (More)
An essential role of the conserved Asp74 in the coupling of the type 1 angiotensin II (AII) receptor (AT1) to phospholipase C has already been reported (Bihoreau, C., Monnot, C., Davies, E., Teutsch,… (More)
We report that mutation of specific residues in the human B2 bradykinin (BK) receptor induces its marked constitutive activation, evaluated through inositol phosphate production in COS-7 cells… (More)
The purpose of this work was to investigate the role of N-glycosylation in the expression and pharmacological properties of the the rat AT1a angiotensin II (AII) receptor. Glycosylation-site… (More)
We report new structural data about the rat liver angiotensin II receptor, which belongs to the AT1 subclass. This receptor has been purified at analytical or semi-preparative levels by a previously… (More)
The differential role of amino acids of the third transmembrane domain on peptide and nonpeptide recognition by the AT1 angiotensin II receptor has been evidenced. The mutation of Ser105 into alanine… (More)
LF 7-0156 (2-[[[2-butyl-1-[(4-carboxyphenyl)methyl]-1H-imidazol- 5-yl]methyl]amino]benzoic acid) is a nonpeptide angiotensin II receptor antagonist selective for the type 1 angiotensin receptor. In… (More)
Phorbol 12-myristate 13-acetate (PMA) can stimulate T-cells via its binding to protein kinase C (PKC). Such a phenomenon occurs when a threshold of concentration as low as 1 nM of PMA is reached.… (More)
The aim of this work was to obtain photoactivatable nonpeptide antagonists of the angiotensin II AT(1) receptor. Based on structure-function relationships, two chemical structures as well as… (More)
