Natriuretic peptide DNP

UniProtKB accession:  P28374

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Exhibits vasodilator, natriuretic and diuretic properties in animal models and human tissues. Acts by stimulating cGMP via the natriuretic peptide receptor 1 (NPR1) (PubMed:16778132). Is a poor agonist of the atrial natriuretic peptide receptor 2 (NPR2). Is not degraded by neutral endopeptidase (NEP/MME). Binds to atrial natriuretic peptide clearance receptor (NPR-C/NPR3), which may be responsible of the removal of DNP from the circulation (PubMed:17475216). Increases calcium uptake and induces histamine release from rat peritoneal mast cells. Increases calcium-activated potassium (KCa) current in gastric antral circular smooth muscle cells by increasing cGMP production and activating inositol trisphosphate receptors (IP3Rs) (PubMed:18096107). In vivo, reduces both systolic and diastolic blood pressure with no effect on heart rate, when intravenously injected in conscious rabbits (PubMed:37049825).
