Cell cycle and ubiquitin signaling

Cell division is instrumental for all living organisms and defects in its regulatory systems are linked to cellular transformation. Cell division requires duplication of all genetic material during S-phase followed by its precise partitioning between two daughter cells during mitosis. The cell cycle machinery involves many critical factors and enzymes that need to be precisely regulated in time and space. Thus, both their timely expression and correct localization to the subcellular compartments must be achieved during different morphological transitions.
Research in our group focuses on the role of the ubiquitin conjugation system in spatio-temporal control of cell division. We are using advanced microscopy and proteomic approaches to identify and characterize the key components of the ubiquitin-conjugation machinery in human cells (E3-ligases, Deubiquitinating enzymes, Ubiquitin-binding proteins) as well as the critical ubiquitination substrates that play a role during cell cycle progression. Our team is particularly interested in understanding the mechanisms coordinating the mitotic events with completion of cytokinesis. Studying the basic molecular mechanisms of cell division will hopefully help us to understand the origins of genomic instability and thereby cellular transformation.

• Current projects

  Our research group will focus on the major question: What are the molecular mechanisms of cell cycle and genome stability?
  Specifically:
  1. What are the molecular mechanisms of faithful cell cycle and how do Cul3-based E3-ligases regulate cell   division?
  2. What are the novel ubiquitination substrates that are required for faithful cell division?
  3. What are the novel components of the ubiquitin system, which are required for mitosis in mammalian
  cells?
  4. What is the role of Cul3 and UPS during cancer development?
