It binds and activates a highly conserved orthosteric ligand-binding domain (LBD) that is present in both ionotropic and metabotropic glutamate receptors (mGluRs) [ 30 ].
WebThe maleimide moiety of MAG binds covalently to the cysteine on the ligand-binding domain of the recep- tor and photoswitching occurs through reversible binding of the glutamate moiety of MAG, in and out of the ligand-binding pocket. MAG binding activates the receptor allowing cations to flow, resulting in membrane depolarization.
