This section provides a summary of the gene/protein's function, expression, and relevance to neurodegenerative diseases.
NPR1 encodes natriuretic peptide receptor 1 (NPR1), also known as guanylate cyclase 1 or ANP receptor. NPR1 is a receptor guanylate cyclase that binds atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and C-type natriuretic peptide (CNP). Upon ligand binding, NPR1 activates guanylate cyclase activity, producing cyclic GMP (cGMP) from GTP. cGMP then activates protein kinase G (PKG), leading to various downstream effects including vasodilation, natriuresis, and inhibition of cell proliferation. In the brain, NPR1 is involved in cardiovascular regulation, memory, and neuroprotection.
High expression in kidney, adrenal gland, lung, and heart. In the brain, expressed in hypothalamus, thalamus, and circumventricular organs. Also expressed in vascular smooth muscle and endothelial cells. NPR1 is present in brain regions involved in cardiovascular control and fluid homeostasis.
