G protein-coupled receptor structure
WebG protein-coupled receptor 55 also known as GPR55 is a G protein-coupled receptor that in humans is encoded by the GPR55 gene. [5] GPR55, along with GPR119 and GPR18, have been implicated as novel cannabinoid receptors. [6] [7] History [ edit] GPR55 was identified and cloned for the first time in 1999. [8] WebMuscarinic ACh receptors (mAChRs) are metabotropic receptors that, depending on their coupling to G-protein α-subunits, can inhibit or excite postsynaptic neurons, while nicotinic ACh receptors (nAChRs) are ligand-gated cation channels that directly excite postsynaptic neurons.
