| Research Abstract |
The increase in the p783 level, which is AMPK-dependent phosphorylation site on GABA_B receptors R2 subunit, suppresses desensitization of the receptors. The p783 level was increased by NMDA exposure in the primary neurons, which were cultured in DMEM-based medium. On the other hand, the phosphorylation site immediately dephosphorylated in vitro system, according to the decrease in AMPK activity. It is thus suggested that GABA_B receptors functions were promptly regulated by the alteration of AMPK activity.
