Research Priorities: Control of protein synthesis, Post-transcriptional control of gene regulation and its disorders in genetic diseases, Regulation of human iron metabolism, Metabolic processes and gene regulation, Riboregulation
Matthias Hentze is a physician. He is currently investigating connections between metabolic processes and gene regulation and how they influence one another. Following his discovery of hundreds of new RNA-binding proteins, he has a particular interest in riboregulation, a biological control mechanism that Hentze’s team also recently newly described.
For many years, his research focused on the control mechanisms of protein synthesis, post-transcriptional control of gene regulation and its disorders in genetic diseases, as well as the regulation of human iron metabolism and how imbalances contribute to disease. Matthias Hentze’s work has made key contributions to the understanding of translational control. A cell must always regulate how much of an enzyme, signal molecule or structural protein it produces. Translation allows a cell to react very quickly to changing conditions and, for example, rapidly produce many proteins. If translational control malfunctions, diseases such as cancer may result.
Hentze also discovered that proteins interact directly with RNA and can influence their functions. He managed to identify several of these riboregulations. He and his team developed investigative methods to analyse protein interactions and understand the role of proteins in genome regulation. He wants to discover which proteins and mechanisms play a key role in the control of gene expression and which dysregulations are linked to diseases.
