Abstract
Covalent labeling has been widely used for structural and functional analyses of proteins. To target a wide range of PDZ domains, we designed a chemical scaffold mimicking the E/D-T/S-XV peptide, which is a PDZ domain that binds ligands in higher occurrence. A chemical probe (2) that contained this moiety alkylated diverse PDZ domains, including NHERF-1 PDZ2, and differentially visualized the cellular proteome.
