"Data suggest that millisecond dynamic changes in PDZ1 domain conformation are responsible for higher affinity of scribble PDZ1 for phosphorylated ligands; oligopeptide fragments of RPS6KA2 and MCC were used as ligands in these nuclear magnetic resonance chemical shift experiments. (RPS6KA2 = ribosomal protein S6 kinase 2; MCC = mutated in colorectal cancer protein)"xsd:string
