H1 Human Histamine GPCR GTPgammaS Antagonist LeadHunter Assay - TW
OVERVIEW
DOCUMENTS/REFERENCES
Biological Information
Background Information:
Histamine receptors belong to the superfamily of G protein-coupled seven transmembrane proteins. G-protein-coupled receptors constitute one of the major signal transduction systems in eukaryotic cells. Coding sequences for these receptors, in those regions believed to contribute to the agonist-antagonist binding site, are strongly conserved across mammalian species. Histamine receptors are found in most peripheral tissue and within the central nervous system.
