Preparation and Storage

Background: NPRC/NPR3

Atrial Natriuretic Peptide Receptor-3 (NPR3), also known as NPRC or ANPR-C, is one of the three natriuretic peptide receptors (1, 2). Mature human NPR3 is a type I transmembrane glycoprotein that contains a 455 amino acid (aa) extracellular domain (ECD), a 23 aa transmembrane segment, and a 37 aa cytoplasmic region. Within the ECD, human NPR3 shares 92% aa sequence identity with mouse and rat NPR3. The natriuretic system is key to the maintenance of vascular tone and cardiovascular homeostasis. It consists of three related natriuretic peptides: atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and C-type natriuretic peptide (CNP). It also consists of three single-membrane-spanning receptors (NPRs) to mediate the biological activity of these peptides: NPR1, NPR2, and NPR3. NPR1 and NPR2 are guanylyl cyclase receptors that regulate cGMP levels, while NPR3 lacks enzymatic activity and may act as a clearance receptor (1, 2). Both ANP and BNP exhibit high binding affinities to NPR1 and NPR3, while CNP binds with high affinity to NPR2 and NPR3 (2). NPR3 is known to be expressed in the heart, lung, adrenal gland, heart, cerebral cortex, cerebellum, liver and adipocytes and in some cancers (1, 2). Osteocrin was found to be a specific ligand to NPR3 (3). NPR3 is necessary for Osteocrin to regulate femoral, tibial, and metatarsal bone elongation (4).
