Research Priorities: Molecular biology, gene transcription, gene regulation, RNA polymerases, three-dimensional structure of enzymes
Patrick Cramer is a chemist and molecular biologist. He researches how cells read out information stored in the genome (gene transcription). He was able to visualize the three-dimensional structure of one of the largest enzymes in the cell nucleus and identified essential parts of the transcription mechanism.
In the tissues of the body, many different proteins fulfil very different tasks. The proteins are produced according to instructions that are stored in the genome. In order to synthesize new proteins, the instruction in the DNA must be read. For this gene transcription, the cells use certain enzymes, so-called RNA polymerases. Patrick Cramer wants to understand how these polymerases work and elucidate the mechanisms of gene transcription and gene regulation.
Together with his team, Cramer has identified the three-dimensional structure of RNA polymerase II of yeast cells and was able to show which cellular factors control it. He was the first to describe the three-dimensional atomic structure of a polymerase in a mammal, the cow. He also recorded the first film of transcription in atomic resolution.
Patrick Cramer wants to further investigate RNA polymerase in mammalian cells and find out how genes are switched on and off at the molecular level and how their activity is controlled. With his research, he wants to completely understand the regulation of gene transcription. To achieve this, he uses structural biological methods such as X-ray crystallography and electron microscopy, as well as methods of bioinformatics and functional genomics. Cramer has expanded the research field of life sciences and contributes to the fields of genome biology and molecular systems biology.
