|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||The H4 subclass of histamine receptors could mediate the histamine signals in peripheral tissues. Displays a significant level of constitutive activity (spontaneous activity in the absence of agonist).|
|Cellular Location||Cell membrane; Multi-pass membrane protein.|
|Tissue Location||Expressed primarily in the bone marrow and eosinophils. Shows preferential distribution in cells of immunological relevance such as T-cells, dendritic cells, monocytes, mast cells, neutrophils. Also expressed in a wide variety of peripheral tissues, including the heart, kidney, liver, lung, pancreas, skeletal muscle, prostate, small intestine, spleen, testis, colon, fetal liver and lymph node|

Histamine is a ubiquitous messenger molecule released frommast cells, enterochromaffin-like cells, and neurons. Its variousactions are mediated by a family of histamine receptors, which area subset of the G-protein coupled receptor superfamily. This geneencodes a histamine receptor that is predominantly expressed inhaematopoietic cells. The protein is thought to play a role ininflammation and allergy reponses. Multiple transcript variantsencoding different isoforms have been found for this gene.
