Background: NPRA/NPR1

Natriuretic peptide receptor A/guanylate cyclase A (NPR1), also called NPRA or GC-A, is a 120‑140 kDa type I transmembrane glycoprotein that is the primary receptor for natrietic peptides ANP and BNP. Binding of ANP to the extracellular ligand binding domain (aa 54‑415), plus ATP to the intracellular kinase homology domain (aa 528‑805) activates a cytoplasmic guanylate cyclase (aa 840‑1023). NPR1 is expressed most highly in kidney, adrenal and adipose tissue. Human NPR1 extracellular domain shows 86%, 44% and 34% aa identity with mouse NPR1, human NPRB and human NPRC, respectively.
