catalytic activity:GTP = 3',5'-cyclic GMP + diphosphate.,function:Receptor for atrial natriuretic peptide. Has guanylate cyclase activity on binding of ANF.,miscellaneous:There seem to be at least three natriuretic peptide hormone receptors: two with guanylate cyclase activity (NPR1/ANP-A and NPR2/ANP-B) and one (NPR3/ANP-C) which is probably responsible for the clearance of natriuretic peptides from the circulation without a role in signal transduction.,PTM:Phosphorylation of the protein kinase-like domain is required for full activation by ANP.,similarity:Belongs to the adenylyl cyclase class-4/guanylyl cyclase family.,similarity:Contains 1 guanylate cyclase domain.,similarity:Contains 1 protein kinase domain.,
Membrane; Single-pass type I membrane protein.
