5-HT2A Human Serotonin GPCR Cell Based Agonist Calcium Flux (in Arrestin Cell Line) LeadHunter Assay - US

Background Information:

Serotonin 5-HT receptors belong to the superfamily of G protein-coupled seven transmembrane proteins with the exception of the 5-HT3 subtype, which belongs to the ligand gated cation superfamily of receptors. 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. Serotonin 5-HT2 receptors are widely distributed in the central nervous system and peripheral tissues. The 5-HT2 receptor class couples preferentially to Gq/G11 to increase hydrolysis of inositol phosphates and elevate cytosolic [Ca2+].

PathHunter β-Arrestin GPCR cell lines are engineered to co-express the ProLink™ (PK) tagged GPCR and the Enzyme Acceptor (EA) tagged β-Arrestin. Activation of the GPCR-PK induces β-Arrestin-EA recruitment, forcing complementation of the two enzyme fragments. The resulting functional enzyme hydrolyzes substrate to generate a chemiluminescent signal. PathHunter cell lines expressing Gq-coupled receptors can also be used to detect calcium mobilization.
