Summaries for HRH3 Gene

Entrez Gene Summary for HRH3 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. This gene encodes one of the histamine receptors (H3) which belongs to the family 1 of G protein-coupled receptors. It is an integral membrane protein and can regulate neurotransmitter release. This receptor can also increase voltage-dependent calcium current in smooth muscles and innervates the blood vessels and the heart in cardiovascular system. [provided by RefSeq, Jul 2008]

GeneCards Summary for HRH3 Gene

HRH3 (Histamine Receptor H3) is a Protein Coding gene. Diseases associated with HRH3 include Hepatic Coma and Kleine-Levin Hibernation Syndrome. Among its related pathways are Peptide ligand-binding receptors 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 HRH4.

UniProtKB/Swiss-Prot for HRH3 Gene

  • 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 neither modified adenylate cyclase activity nor induced intracellular calcium mobilization.

Tocris Summary for HRH3 Gene

  • Histamine H3 receptors are Galphai/o-protein-coupled receptors expressed at high levels on histaminergic neurons in the CNS, particularly in the basal ganglia, cortex and hippocampus. H3 receptors are thought to function as presynaptic autoreceptors.

Tissue specificity: Expressed predominantly in the CNS, with the greatest expression in the thalamus and caudate nucleus. The various isoforms are mainly coexpressed in brain, but their relative expression level varies in a region-specific manner. Isoform 3 and isoform 7 are highly expressed in the thalamus, caudate nucleus and cerebellum while isoform 5 and isoform 6 show a poor expression. Isoform 5 and isoform 6 show a high expression in the amygdala, substantia nigra, cerebral cortex and hypothalamus. Isoform 7 is not found in hypothalamus or substantia nigra.
