Profile

Professor Thomas Schalch has a keen interest in understanding how eukaryotic genomes work. He is an expert in structural biology and biochemistry with a focus on chromatin structure and function.


Research

The Schalch Lab specializes in exploring the structural and biochemical principles underpinning genome organization, with a particular focus on chromatin's role in gene regulation and its implications for cancer. Our research spans several key areas:

  1. Chromatin Structure and Gene Regulation: Investigating how chromatin fiber structure within the nucleus influences gene activity.
  2. Ubiquitination and Chromatin Signaling: Studying the role of ubiquitin in modulating chromatin dynamics, particularly how H2B ubiquitination prevents heterochromatin spread over active genes.
  3. Histone Modification and Heterochromatin Formation: Exploring the regulation of the Clr4 methyltransferase in heterochromatin assembly and gene silencing.

Our methodologies include X-ray crystallography, cryo-EM, genetic, and biochemical experiments, primarily using the fission yeast S. pombe as a model. We aim to elucidate the three-dimensional organization of chromatin and its impact on genome function, contributing to a deeper understanding of cellular mechanisms and potential therapeutic strategies.
