WebTARPs are non-pore-forming integral membrane proteins with four transmembrane domains (thus resembling tetraspanins) that directly interact with AMPARs [ 4, 5, 6, 7, 8, 9, 10 ]. They are expressed differentially all over the brain, and γ2 in particular is expressed in every type of neuron [ 11 ]. WebGlutamate α-Amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors (AMPARs) regulate chronic alcohol self-administration in preclinical models. Recent evidence indicates that the expression and function of AMPARs require the transmembrane AMPAR regulatory protein γ-8 (TARP γ-8).
