Research by Michel Steinmetz

Proteins and their interaction networks are at the heart of life. Understanding how diverse and complex proteins come together spatially and temporally and how their specific interactions translate into cellular functions represents a major challenge. Our group uses X-ray crystallography in combination with biochemical and biophysical methods to investigate protein interactions implicated in the regulation of the microtubule cytoskeleton. Microtubules are filamentous structures fundamentally involved in many diverse cellular processes ranging from cell division, motility and intracellular transport. Because of its important role for cell viability, malfunction of the microtubule cytoskeleton is associated with many human pathologies including cancer, cardiovascular and neurodegenerative disorders. We are investigating the nature, modes of regulation, and the structural and biophysical properties of protein interaction networks regulating the microtubule cytoskeleton.
