GSSG, along with glutathione and
S-nitrosoglutathione (GSNO), have been found to bind to the
glutamate recognition site of the
NMDA and
AMPA receptors (via their γ-glutamyl moieties), and may be
endogenous neuromodulators. At
millimolar concentrations, they may also modulate the redox state of the NMDA receptor complex. ==See also==
