Summaries for HRH2 Gene

Entrez Gene Summary for HRH2 Gene

  • Histamine is a ubiquitous messenger molecule released from mast cells, enterochromaffin-like cells, and neurons. Its various actions are mediated by histamine receptors H1, H2, H3 and H4. Histamine receptor H2 belongs to the family 1 of G protein-coupled receptors. It is an integral membrane protein and stimulates gastric acid secretion. It also regulates gastrointestinal motility and intestinal secretion and is thought to be involved in regulating cell growth and differentiation. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

GeneCards Summary for HRH2 Gene

HRH2 (Histamine Receptor H2) is a Protein Coding gene. Diseases associated with HRH2 include Duodenal Ulcer and Peptic Ulcer Disease. Among its related pathways are Monoamine GPCRs and Signaling by GPCR. Gene Ontology (GO) annotations related to this gene include G-protein coupled receptor activity and histamine receptor activity. An important paralog of this gene is ADRB1.

UniProtKB/Swiss-Prot for HRH2 Gene

  • The H2 subclass of histamine receptors mediates gastric acid secretion. Also appears to regulate gastrointestinal motility and intestinal secretion. Possible role in regulating cell growth and differentiation. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase and, through a separate G protein-dependent mechanism, the phosphoinositide/protein kinase (PKC) signaling pathway (By similarity).

Tocris Summary for HRH2 Gene

  • Histamine H2 receptors are Galphas-protein-coupled receptors involved in the suppressive activities of histamine. H2 receptors exhibit a widespread distribution and are found in the gastrointestinal tract, the central nervous system, smooth muscle cells and endothelial cells.
