Metabolite Identification
Common NameBetazole
DescriptionBetazole is only found in individuals that have used or taken this drug. It is a histamine H2 agonist used clinically to test gastric secretory function. [PubChem]Betazole is a histamine analogue. It produces the same effects as histamine, binding the H2 receptor which is a mediator of gastric acid secretion. This agonist action thereby results in an increase in the volume of gastric acid produced.

Enzymes

General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
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
Gene Name:
HRH2
Uniprot ID:
P25021
