A previous study reported that phosphorylation of the Kv3 channel could influence its currents.[24] We analyzed Kv3.1 and Kv3.2 phosphorylation levels and found that the Kv3.2 channel phosphorylation level in MD neurons of mice with PTSD was significantly lower than that in WT mice, but that of the Kv3.1 channel remained unchanged (Figure 7I–L; Figure S15, Supporting Information). This evidence concerns the gene KCNC2 and post-traumatic stress disorder.
