We report a general method for light-assisted control of interactions of PDZ
domain binding motifs with their cognate domains by the incorporation of a
photolabile caging group onto the essential C-terminal carboxylate binding
determinant of the motif. The strategy was implemented and validated for both
simple monovalent and biomimetic divalent ligands, which have recently been
established as powerful tools for acute perturbation of native PDZ
domain-dependent interactions in live cells.
