Regulation of AMPAR trafficking by TARP γ3, γ4, γ7, and γ8, CNIH and GSG1L. TARP γ3, γ4, γ7, and γ8, CNIH2 and 3, and GSG1L modulate AMPAR trafficking to and at the synapse. γ3, γ4, and γ8 and CNIH2 together, target AMPARs to the extrasynaptic pool. γ8 and CNIH2 also cooperatively regulate AMPAR lateral diffusion to and anchoring at the synapse, by binding MAGUK proteins. TARP γ7 and CNIH3 are also present at the synapse. GSG1L, on the other hand, promotes AMPAR endocytosis and negatively regulates AMPAR trafficking to the synapse
