Site directed mutation of T91 to alanine abolished PKA mediated phosphorylation and inhibition of GAD activity

:
PKA inhibitor restored GAD67 activity and GABA levels in IH treated cells ... These results provide evidence for the role of D1R-cAMP-PKA signaling in IH-mediated inhibition of GAD67 via protein phosphorylation resulting in down-regulation of GABA synthesis
