q GPCR assays

Gq -coupled G protein-coupled receptors (GPCRs) are a subset of GPCRs that couple with the Gαq protein subunit.

16 GPCR assays

16 is a promiscuous Gαq protein subunit that can couple to a wide variety of receptors including Gαi/o and Gα12/13 GPCRs. The downstream signaling cascade of GPCR ligand binding includes activation of phospholipase C-β, an increase in IP3, and a release of calcium from intracellular stores like other Gq-coupled GPCRs. This chimeric G protein can be over-expressed in HEK293 and other mammalian cell lines to enable calcium signaling as a functional readout of GPCR activity, and is commonly used to uncover native ligands for orphan GPCRs.
