*As explored further in [[#Transmembrane domain architecture and the occluded pore|a later section below]] , the <scene name='User:Wayne_Decatur/Sandbox_Glutamate_receptor/Tmd_domain_4fold/2'>symmetry is an overall four-fold for the TMD</scene>. Thus, remarkably, the symmetry switches from an overall two-fold symmetry for the ATD and LBD to four-fold for the TMD.

As a result of the swapping and symmetry mismatch, there is subunit non-equivalence; even though all the chains are the same chemically, there are two distinct conformations of the subunits. This means there are two matching pairs of subunits.
