*The TMD domain of the GluA2 receptor shares structural and sequence similarity with the pore region of the potassium (K+), as hinted at by earlier work<ref name ="pot1">PMID: 7539962</ref><ref name ="pot2">PMID: 7761417</ref><ref name ="pot2">PMID: 9525859</ref>. Here the pore region of ''Streptomyces lividans'' potassium channel ([[1bl8]])<scene name='User:Wayne_Decatur/Sandbox_Glutamate_receptor/Gluvspottmd/4'>superposed with the TMD domain with GluA2</scene>, specifically the inner helix of the K+ channel aligned with the M3 segment. M1 also overlays well with the outer helix of the K+ channel. | |||
