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 sleep disorder. GO annotations related to this gene include histamine receptor activity. An important paralog of this gene is HTR2A.

UniProtKB/Swiss-Prot: HRH3_HUMAN, Q9Y5N1

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 neither modified adenylate cyclase activity

nor induced intracellular calcium mobilization

summary for HRH3 Gene:

Histamine H3 receptors are Galphai/o-protein-coupled receptors first cloned in 1999. H3 receptors are

expressed at high levels on histaminergic neurons in the central nervous system, particularly in the basal

ganglia, cortex, hippocampus and strial area. They are expressed in the periphery at lower densities in the

gastrointestinal, bronchial and cardiovascular systems. H3 receptors are thought to function as presynaptic

autoreceptors, and activation stimulates the negative feedback mechanism that reduces central histaminergic

activity. These receptors have displayed heterogeneity in binding and functional studies, suggesting

multiple subtypes. In rats, three H3 receptor subtypes have been indentified and they all vary in the length

of the third extracellular loop, have distinct CNS localization and differentially couple to adenylyl

cyclase and MAPK signaling pathways. H3 receptors have multiple functions including roles in cognition,

sleep-wake status, energy homeostasis regulation and inflammation. Activation of these receptors can inhibit

histamine, dopamine, serotonin, noradrenalin and acetylcholine release and they participate in control of

neurogenic inflammation through local-neuron feedback loops. Furthermore, H3 receptor activation increases

antigen-presenting cell capacity. H3 receptors are thought to have pathophysiological relevance and are

involved in cognitive impairment, seizures and possibly metabolic syndrome. The human gene encoding this

receptor is localized to chromosome 20q13.33.

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
