WebMar 3, 2013 · These findings led us to synthesize D-MAG-0 and D-MAG-1 (D-maleimide azobenzene glutamate; Fig. 1b) with the goal of identifying attachment points for optical agonism or antagonism . 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.
