Research

The ability to sequence entire genomes and transcriptomes in ever shorter timeframes has far outpaced our understanding of how gene expression is controlled. Even though we have a firm knowledge of the general principles of gene expression, we are still far from a holistic and comprehensive understanding of the underlying regulation. It is one of the major challenges in modern biology to gain detailed understanding of the regulatory principles and networks that control gene expression.

In recent years, facilitated by new technology and the development of novel methods, evidence accumulated for a surprising discrepancy between the cellular transcriptome and the proteome in eukaryotic cells. Several large-scale datasets show only limited overlap between cellular mRNA abundance/diversity and the corresponding proteome. This appears to be based on differences in both protein synthesis- and decay-rates, with protein abundance being mostly controlled at the level of translation. These findings have fueled the hypothesis that translational regulation might play a role far more important than initially anticipated, fine tuning the levels of a many cellular proteins. However, our understanding of the basic principles and underlying mechanisms of regulation is still rather limited and we are just beginning to see the complexity of eukaryotic translation.

In the lab we are combining global, systems-biology approaches with reductionist, mechanistic experimentation to gain a deeper understanding of translational control.

Financial Support

We are extremely grateful for the generous support that we receive from a number of funding agencies! Without this support we would not be able to pursue our work and to experimentally address intriguing biological questions.
