A simple in silico procedure is proposed with a view to predict the agonist or antagonist character of new, AMPA-type Glu receptor channel ligands. Based on the experimental binding domain structures, the orientation of a single Lys residue close to the ligand binding core was found to be diagnostic of ligand-induced conformational changes. Acting as a switch, the position of the Lys residue indicates the agonist or antagonist character of AMPA receptor ligands, known to bind to the receptor. Stability centre analysis substantiated the key role this switch might play in ligand-induced conformational changes.
