Interaction of the hub protein DYNLL with LC8 peptide

LC8 dynein light chain (DYNLL) is a hub protein, capable of binding proteins of various functions and influence their action. Being a dimeric protein with two equal binding sites it is thought to function as a dimerization engine. The structure of its complex with a high affinity binding peptide developed by in vitro evolutionary technique was determined by X-ray crystallography for characterizing specific interactions of the protein. In the complex the peptide was dimerized by a designed leuzine zipper in order to mimic the natural dimer binding to dimer mechanism and study possible distortion of the interactions in the dimer to dimer complex.
