1. In the CA1 hippocampal pyramidal cell, GluK2 traffics to the neuronal surface and synapse efficiently and the auxiliary subunits Neto1 and Neto2 caused no further enhancement of these two trafficking processes. GluK2 caused a more than 10-fold increase in synaptic transmission. It is the amino-terminal domains of GluK1 and GluK2 that control their strikingly different trafficking properties. PMID: 28100490

7. These findings indicate that ligand binding to only the GluK5 subunit is both necessary and sufficient to allow trafficking of recombinant GluK2/K5 heteromers to the cell membrane, but that occupancy of the GluK2 site alone is not. PMID: 23975096
8. characterized 3 GluK2 apical mutants with attenuated desensitization and identified conformational changes underlying their functional phenotypes; propose that the charge balance in the GluK2 LBD dimer interface maintains a degree of instability, necessary for rapid and complete desensitization PMID: 23720540

19. S-nitrosylation levels of Bcl-2 are down-regulated after kainate injection and the GluR6 (glutamate receptor 6) antagonist NS102 can inhibit the denitrosylation of Bcl-2 PMID: 21148565

28. The GluR6 S1S2 domain has 4 nearby AAs differing between AMPA & kainate subunits. This contributes to their different desensitization kinetics. A common desensitization mechanism depends on binding domain dimer interface stability. PMID: 17005866
