RESEARCH SUMMARY

Dr. Kyung Lee carries out pioneering research aimed at understanding the structure and function of centrosomal self-assemblies and their associated regulatory complexes in human cells. He combines cell biology, structural biology, and cryo-EM to investigate how pericentriolar proteins organize themselves and serve as a platform to physicochemically regulate centriole duplication in a three-dimensional space. A failure in this process can result in abnormal centrosome numbers, improper spindle formation, and chromosome missegregation that leads to genomic instability culminating in genetic disorders such as cancer, microcephaly, ciliopathy, and dwarfism. Dr. Lee has also been investigating the function of mammalian polo-like kinase 1 (Plk1) and has been developing small molecule inhibitors that have potential as anti-cancer therapeutics. Through collaborations with Dr. Ken Jacobson at the National Institute of Diabetes and Digestive and Kidney Diseases, as well as multiple teams at the National Center for Advancing Translational Sciences, Dr. Lee has been steering a drug discovery program to develop inhibitors that target the noncatalytic polo-box domain (PBD) of Plk1, a unique protein-protein interaction module critical for substrate recognition. PBD inhibitors could present a new avenue for overcoming the hurdles currently facing anti-Plk1 therapy and may offer improved therapeutic potential.
