Research Interests


-       Establishing the role of a nuclear regulator of the 20S core proteasome, PA28g, in the response of cells to DNA damage, in the dynamics of nuclear organization and in the resistance of leukemia cells to chemotherapy


-       Identifying new targets of PA28g by SILAC quantitative proteomics


-       Investigating the role of a newly identified protein, PIP30, in the regulation of PA28g activity
