Anti-Pro-Atrial Natriuretic Peptide Antibody, clone 11E3.9 clone 11E3.9, from mouse

Natriuretic peptides A (UniProt P01160; also known as Atriopeptin, Cardiodilatin, Cardiodilatin-related peptide, Cardionatrin, CDD, CDD-ANF, CDP, Natriuretic peptide precursor A, Prepronatriodilatin) is encoded by the NPPA (also known as ANF, ANP, ATFB6, ATRST2, PND) gene (Gene ID 4878) in human. Atrial natriuretic peptide (ANP), also called atrial natriuretic factor, is a cardiac hormone that reduces high blood pressure by promoting salt excretion, decreasing blood volume, and relaxing vessel tension in a receptor-dependent manner. Deficiency in either ANP or its receptor causes spontaneous hypertension in knockout mice. ANP is initially synthesized in cardiac myocytes as a 153 a.a. precursor with a signal (a.a.1-25) and a propeptide (a.a. 26-123) sequence. The removal of the signal peptide yields pro-ANP (a.a. 26-151), which is further cleaved by the transmembrane cardiac serine protease Corin to yield mature ANP (a.a. 124-151), also known as atrial natriuretic factor (ANF). ANP is a short-lived molecule partly due to its proteolytic degradation by the kidney Neprilysin, also known as neutral endopeptidase 24.11.
