Research

My lab aims to identify novel protein interactions dependent on phosphorylation between DNA damage response proteins. We also aim to identify kinases, responsible for phosphorylation, and discover their precise function in the DNA damage response.

We hope that our work will bring deeper understanding of the DNA damage response, its regulation and interplay with other cellular processes. Understanding how DNA damage repair is carried out and regulated is essential for identification and further development of new and more efficient cancer treatments.

DNA is continually exposed to damaging agents such as UV light or products of cellular metabolism. Exposure to these agents can result in damage leading to harmful DNA mutations. Such mutations can deregulate cellular division and development and subsequently trigger transformation of normal cells into cancer cells. Cells therefore have DNA damage repair mechanisms, which are essential for their survival and act as an anti-cancer barrier.

The DNA repair mechanisms are controlled and regulated by phosphorylation signalling, which can activate or deactivate phosphorylated proteins or create or unique binding sites for other proteins. Mutations of kinases that carry out phosphorylation involved in DNA damage response or mutations of their target sites in DNA damage repair proteins are frequently found in tumours. At the same time drugs that inhibit enzymatic activity of the already known kinases regulating DNA damage response are already used as cancer chemotherapeutics.

Biography

• 2016 I received Sir Henry Dale Fellowship and joined Barts Cancer Institute as a lecturer at the Centre of Molecular Oncology.
• 2014 Senior Scientific Officer in the DNA Damage Response Laboratory, Clare Hall Laboratories, The Francis Crick Institute, London, UK. I continued on discovering new phosphorylation events important for regulation of the DNA Damage Response.
• 2007 Postdoctoral Fellow in the DNA Damage Response Laboratory, Clare Hall Laboratories, London Research Institute, Cancer Research UK, London, UK, led by Dr Boulton. I have been studying the role of Casein Kinase 2 in DNA damage response and discovered a new phospho-bidning domain PIH-N.
• PhD viva in 2006 at Charles University in Prague. The main part of my PhD work was done under supervision of Prof Bartek at the Department of Cell Cycle and Cancer, Institute of Cancer Biology, Danish Cancer Society, Copenhagen, Denmark. I was investigating the role of the DNA damage checkpoint in normal and cancer cell cycle.
• MSc degree in 2001 at Charles University in Prague, Czech Republic. The thesis was carried out at Department of Molecular Virology, Institute of Molecular Genetics, Czech Academy of Sciences, Prague, Czech Republic, under supervision of Dr Dvorak. I was studying the role of transcription factor c-Myb in the development and differentiation of the red blood cells.
