THE THIRD PDZ DOMAIN FROM THE SYNAPTIC PROTEIN PSD-95
Overview
Modular PDZ domains, found in many cell junction-associated proteins, mediate the clustering of membrane ion channels by binding to their, C-terminus. The X-ray crystallographic structures of the third PDZ domain, from the synaptic protein PSD-95 in complex with and in the absence of its, peptide ligand have been determined at 1.8 angstroms and 2.3 angstroms, resolution, respectively. The structures reveal that a four-residue, C-terminal stretch (X-Thr/Ser-X-Val-COO(-)) engages the PDZ domain through, antiparallel main chain interactions with a beta sheet of the domain., Recognition of the terminal carboxylate group of the peptide is conferred, by a cradle of main chain amides provided by a Gly-Leu-Gly-Phe loop as, well as by an arginine side chain. Specific side chain interactions and a, prominent hydrophobic pocket explain the selective recognition of the, C-terminal consensus sequence.
