The primary focus of our laboratory is on the investigations of the molecular mechanisms of replication fork arrest, genome stability, checkpoint controls using Saccharomyces cerevisiae and Schizosaccharomyces pombe as model systems. These are topics of intense current interest not only from the perspectives of eukaryotic DNA transactions but also of Cancer Biology. Our laboratory is also interested in the molecular analysis of the human “timeless” protein and TIPIN (timeless-interacting protein).
Our laboratory offers outstanding training in nucleic acids biochemistry, enzymology of DNA replication and on protein nucleic acids and protein-protein interactions.
