One possible interpretation of the available agonist-bound non-conducting KAR structures in pseudo four-fold and asymmetric LBD conformation is that they represent different steps of the desensitization process, which starts similar to AMPARs, with the rupture of D1-D1 interfaces in two intact LBD dimers, followed by dissociation of one LBD dimer and then the second (Zhou et al., 2025)
