Protein interaction domains of about 70-90 amino acid residues, named after a common structure found in PSD-95, Discs Large, and Zona Occludens 1 proteins. PDZ domains are involved in the recruitment and interaction of proteins, and aid the formation of protein scaffolds and signaling networks. This is achieved by sequence-specific binding between a PDZ domain in one protein and a PDZ motif in another protein.
