The cytoskeleton in cell division, development and neuromuscular function.

The research of the Suprenant laboratory is focused on molecular mechanisms of microtubule-associated protein function. We combine studies of the basic biochemistry and molecular biology of microtubules and microtubule-associated proteins, high-resolution time-lapse microscopy of microtubule dynamics, and genetic analyses of protein function.
