Target Background

Receptor for the atrial natriuretic peptide NPPA/ANP and the brain natriuretic peptide NPPB/BNP which are potent vasoactive hormones playing a key role in cardiovascular homeostasis. Has guanylate cyclase activity upon binding of the ligand.
Gene References into Functions
  1. These results of the distinct presence of NPRA and NPRBpositive cells in unstable plaques underlying acute myocardial infarction suggested that natriuretic peptides serve a role in regulating plaque instability in humans. PMID: 28765884

  3. Data suggest that signaling via ANP/ANPR (atrial natriuretic factor/ANP receptor) in vascular endothelial cells activates PAK4 (p21-activated kinase 4) and CCM2 (cerebral cavernous malformation 2 protein), resulting in phosphorylation of MLC (myosin light chain), cytoskeletal reorganization, and cell spreading; kinase homology domain of ANPRA (guanylyl cyclase-A) activates downstream targets of ANP/ANPR signaling. PMID: 28432261
