ANPA natriuretic peptide receptor A, which mediates natriuretic, diuretic, and vasorelaxing actions of the natriuretic peptides. Contains five functional domains: an extracellular ligand-binding domain, a single membrane-spanning region, and intracellularly a protein kinase homology domain, a helical hinge region involved in oligomerization, and a carboxyl-terminal guanylyl cyclase catalytic domain. Belongs to the adenylyl cyclase class-4/guanylyl cyclase family. Has guanylate cyclase activity on binding of ANF. Hypertensive SHR Rat has polymorphism at the locus. Human non-coding polymorphisms can alter expression up to two-fold, and have been associated with hypertension. A coding SNP is associated with hypertension and myocardial infarction.
