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. Histamine H3 receptors on nerve terminals function as feedback inhibitors in a wide variety of organ systems.
