Research Interests:

The Reck-Peterson lab is broadly interested in the regulated movements of intracellular components, which allow cells to move, divide, communicate with neighboring cells, and maintain cellular homeostasis. Most eukaryotic cells are too large to rely on diffusion for these movements. Cells use molecular motors to transport intracellular components quickly in a manner that can be regulated in time and space. 

Intracellular transport occurs along actin and microtubule tracks and is driven by myosins (actin-based motors) and dyneins and kinesins (microtubule-based motors). We focus on microtubule-based intracellular transport. Microtubules, which are larger and more rigid than actin filaments, are typically used for long distance, directed transport.

All eukaryotic cells use motors for transport. In humans, longer cells, such as neurons, are more sensitive to defects in transport. For example, neurodegenerative and neurodevelopmental diseases are known to result from defects in microtubule-based transport.

We use a wide variety of experimental techniques (genetics, genomics, single molecule biophysics, biochemistry, and structural biology) and intellectual frameworks (cell biology, systems biology, synthetic biology, and biophysics) to understand the molecular basis of intracellular transport.
