Research interests:
The organization and function of chromatin, the physiological template for all nuclear processes involving genetic information, are largely dictated by posttranslational histone modifications. Our laboratory has been focused on studying one of these modifications, histone ubiquitination. By following the enzymatic activities, we have recently identified several enzymes that are responsible for ubiquitination and deubiquitination of histone H3, H4, H2A, H2B, and H1. Further characterization indicates that these enzymes play critical roles in gene expression, cell cycle control, and DNA damage repair (see publication list). We are currently investigating the roles of these enzymes in stem cell function, embryogenesis, and cancer development. We employ a combination of biochemical and genetic approach to decipher the functions of these histone modifying enzymes in chromatin and cellular regulation. People with strong Interests in chromatin and epigenetics are encouraged to apply.
