Dynamic gene regulation
We study changes in coding properties for DNA, RNA and amino acids of proteins, and the factors responsible for these changes.
Recent research has unraveled a remarkable diversity of chemical modifications that modify the coding properties of bases in DNA and RNA and the amino acids of a protein.
Our aim is to identify writers, readers and erasers of such marks and to gain understanding of their biological relevance.
We are particularly interested in reprogramming of the human genome in meiosis and the preimplantation embryo. Moreover, novel mechanisms for gene-regulation might be crucial for understanding cancer development.
Our current studies also include several novel models for post translational modifications in RNA. The reversible nature of some chemical modifications of RNA is a very recent discovery. Most of our studies rely on novel mutants in various model organisms.
- Identify molecular mechanisms underlying coding properties of methylated adenines in mRNA
- Understand meiotic failure in mice lacking mRNA demethylases
- Investigate gene-regulation in the maturation of sperm and egg, including meiosis
- Study genome regulation in the maternal to zygotic transition
- Stem cell biology
