Identification
HMDB Protein ID HMDBP02715
Secondary Accession Numbers
  • 8218
Name Histamine H3 receptor
Synonyms
  1. G-protein coupled receptor 97
  2. H3R
  3. HH3R
Gene Name HRH3
Protein Type Unknown
Biological Properties
General Function Involved in G-protein coupled receptor protein signaling pathway
Specific Function The H3 subclass of histamine receptors could mediate the histamine signals in CNS and peripheral nervous system. Signals through the inhibition of adenylate cyclase and displays high constitutive activity (spontaneous activity in the absence of agonist). Agonist stimulation of isoform 3 niether modified adenylate cyclase activity nor induced intracellular calcium mobilization
