Welcome to the Grishchuk Lab
Our goal is to understand the molecular mechanisms that produce force and accuracy for mitotic chromosome motions during cell division. We use biophysical, cell biological and computational approaches to study kinetochore proteins, which function as efficient nanomachines: they can capture the energy from microtubule disassembly and provide lasting attachments between the chromosomes and dynamic microtubule ends. There are no man-made or natural macro-devices that function analogously to these couplers, so understanding their principle mechanisms presents a significant challenge. Rigorous understanding of how microtubules attach to chromosomal kinetochores should ultimately assist developing novel and more specific anticancer drugs.
