Description | Rabbit IgG polyclonal antibody for Histamine H3 receptor(HRH3) detection. Tested with WB in Human;Mouse;Rat. |
Reconstitution | Add 0.2ml of distilled water will yield a concentration of 500ug/ml. |
Gene ID | 11255 |
---|---|
Other Names | Histamine H3 receptor, H3R, HH3R, G-protein coupled receptor 97, HRH3, GPCR97 |
Calculated MW | 48671 MW KDa |
Application Details | Western blot, 0.1-0.5 µg/ml, Human, Rat, Mouse |
Subcellular Localization | Cell membrane; Multi-pass membrane protein. |
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. |
Protein Name | Histamine H3 receptor(H3R/HH3R) |
Contents | Each vial contains 5mg BSA, 0.9mg NaCl, 0.2mg Na2HPO4, 0.05mg Thimerosal, 0.05mg NaN3. |
Immunogen | A synthetic peptide corresponding to a sequence at the C-terminus of human HRH3(428-445aa CPQKLKIQPHSSLEHCWK), different from the related rat sequence by three amino acids. |
Purification | Immunogen affinity purified. |
Cross Reactivity | No cross reactivity with other proteins |
Storage | At -20˚C for one year. After r˚Constitution, at 4˚C for one month. It˚Can also be aliquotted and stored frozen at -20˚C for a longer time.Avoid repeated freezing and thawing. |
Name | HRH3 |
---|---|
Synonyms | GPCR97 |
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. |
Cellular Location | Cell membrane; Multi-pass membrane protein. |
Tissue Location | 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 |

Background
The histamine receptor H3(HRH3) is a presynaptic autoreceptor on histamine neurons in the brain and a presynaptic heteroreceptor in nonhistamine-containing neurons in both the central and peripheral nervous systems. The deduced 445-amino acid HRH3 protein contains 7 predicted transmembrane domains. And it shares 22% and 21.4% amino acid sequence homology with the H1(HRH1) and H2(HRH2) receptors, respectively. The expression of recombinant HRH3 in a variety of cell lines conferred an ability to inhibit adenylate cyclase in response to histamine, but not to acetylcholine or any other biogenic amine. Additionally, HRH3 was most notably observed throughout the thalamus, the ventromedial hypothalamus, and the caudate nucleus. Strong expression was also seen in layers II, V, and VIb of the cerebral cortex, in the pyramidal layers of the hippocampus, and in olfactory tubercle.
