Guanylyl cyclases, catalyzing the production of cGMP from GTP, are classified as soluble and membrane forms (Garbers and Lowe, 1994 [PubMed 7982997]). The membrane guanylyl cyclases, often termed guanylyl cyclases A through F, form a family of cell-surface receptors with a similar topographic structure: an extracellular ligand-binding domain, a single membrane-spanning domain, and an intracellular region that contains a protein kinase-like domain and a cyclase catalytic domain. GC-A and GC-B function as receptors for natriuretic peptides; they are also referred to as atrial natriuretic peptide receptor A (NPR1) and type B (NPR2; MIM 108961). Also see NPR3 (MIM 108962), which encodes a protein with only the ligand-binding transmembrane and 37-amino acid cytoplasmic domains. NPR1 is a membrane-bound guanylate cyclase that serves as the receptor for both atrial and brain natriuretic peptides (ANP (MIM 108780) and BNP (MIM 600295), respectively).[supplied by OMIM, May 2009]
GeneCards Summary for NPR1 Gene
NPR1 (Natriuretic Peptide Receptor 1) is a Protein Coding gene. Diseases associated with NPR1 include hypertensive heart disease and breast adenocarcinoma. Among its related pathways are CREB Pathway and Nanog in Mammalian ESC Pluripotency. GO annotations related to this gene include GTP binding and protein kinase activity. An important paralog of this gene is ADCY5.
UniProtKB/Swiss-Prot for NPR1 Gene
Receptor for the atrial natriuretic peptide NPPA/ANP and the brain natriuretic peptide NPPB/BNP which are potent vasoactive hormones playing a key role in cardiovascular homeostasis. Has guanylate cyclase activity upon binding of the ligand.
Natriuretic peptide (NP) receptors are single transmembrane catalytic receptors with intracellular guanylyl cyclase activity. There are three isoforms of NP receptors; NPR1, NPR2 and NPR3, which have conserved catalytic and regulatory domains and divergent ligand binding domains. Natruiretic peptide receptors bind alpha-atrial natriuretic peptide, brain natriuretic peptide and type C-natriuretic peptide with varying affinity and are found in the brain, vasculature and kidney. The main physiological role of NP receptors is in homeostasis of body fluid volume.
