Our laboratory is interested in understanding the function of chromatin regulators (transcription factors and chromatin remodelers) in cancer. Recent large-scale genome profiling revealed frequent mutations on chromatin regulator genes in various cancers. By using a combination of genomics, biochemistry, and genome editing techniques, we study basic mechanisms and cancer specific functions of chromatin regulators.
