Abstract excerpt
To define the ligand-binding site of natriuretic peptide receptor (NPR), amino acid substitutions were carried out by site-directed mutagenesis at selected residues of bovine NPR-C. The mutant receptors were expressed in COS-1 cells and the effect of the mutations on the binding of ligand was analyzed by binding assay, affinity labeling, and immunoblotting. The replacement of His145-Trp146 (HW) by Leu145-Leu146...
