|a A systematic and general approach for identifying efficient probes for class I PDZ domains based on environment-sensitive chromophores is presented. A series of peptides derived from the C-terminal sequence of Stargazin was first used with PDZ domains of PSD-95 and Shank3 to identify the optimal position and linker length for the 4-DMAP chromophore. The results were applied to well-characterized ligand sequences for each set of domains to generate high affinity probes that retain their native sequence specificity and yield remarkable fluorescence increases upon binding. These probes constitute efficient tools to study the dynamics and regulatory mechanisms of PDZ domain-mediated interactions.
