Using an antiserum raised against the purified atrial natriuretic peptide (ANP) receptor that has a disulfide-linked homodimeric structure and represents one subtype of the multiple ANP receptors, we showed that the receptor is coupled to the guanylate cyclase activation; formerly, this type of ANP receptor is not considered to be coupled to the cyclase.(More)
Vascular endothelial cells have been shown to contain atrial natriuretic peptide (ANP)-sensitive Na-K-Cl cotransport system whose activity is regulated by intracellular cGMP levels. Addition of ANP to culture medium stimulated 86Rb+ uptake in bovine endothelial cells with a concomitant increase in cGMP contents. This action of ANP was mimicked by(More)
The interaction between the receptor (Rc) for atrial natriuretic peptide (ANP) and the effector enzyme particulate guanylate cyclase (GC) has been studied by radiation inactivation. Irradiation of bovine lung membranes produced an increase in GC activity at low radiation doses followed by a dose-dependent reduction at higher doses. This deviation from(More)
