Primary Drug Target
NameHistamine H2 Receptor
Gene NameHRH2
SynonymsHistamine H2 receptor; H2R; Gastric receptor I
Specific FunctionThe 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
