Welcome to the Liu Research Group


Alteration or loss of the p53 tumor suppressor gene is the most frequent lesion detected in cancer. In normal cells, the p53 protein plays a critical role in the regulation of cell proliferation, serving as a checkpoint function to monitor DNA damage and to arrest cell division prior to replication. The biochemical activity of p53 that is required for this relies on its ability to bind to specific DNA sequences and to function as a transcription factor. Our laboratory is interested in understanding the molecular mechanisms by which p53 functions as a transcription factor and by which cells regulate p53 transcriptional activity. In this regard, our research has focused on the following 3 areas: 1) understanding molecular interplay between p53 and a cell cycle protein TAF1; 2) characterizing regulation of p53 by B56 gamma-specific PP2A; and 3) defining crosstalk between p53 and the PTEN tumor suppressor pathways.
