NPRA/NPR1 Proteins and Enzymes

Natriuretic peptide receptor A/guanylate cyclase A (NPRA), also called NPR-1 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) activ...
