Summaries for NPR1 Gene

Entrez Gene Summary for NPR1 Gene

  • 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 Congestive Heart Failure and Acromesomelic Dysplasia. Among its related pathways are Nanog in Mammalian ESC Pluripotency and Regulation of lipolysis in adipocytes. GO annotations related to this gene include transferase activity, transferring phosphorus-containing groups and protein tyrosine kinase activity. An important paralog of this gene is NPR2.

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.

Tocris Summary for NPR1 Gene

  • Natriuretic peptide (NP) receptors are single transmembrane catalytic receptors with intracellular guanylyl cyclase activity. There are three isoforms of NP receptors; NPR1-3, which have conserved catalytic and regulatory domains and divergent ligand binding domains.
