The inside of a cell is both incredibly crowded and extremely organized. It is the organization within a cell that allows it to be an exciting environment capable of the functions associated with life. Important players in a cell’s ability to stay ordered are motor proteins. These microscopic engines allow a cell to transport, compartmentalize, and arrange its components by generating force and creating motion. However, this motion occurs at the microscopic scale of the cell, where all biomolecules are constantly undergoing violent, jittery motions due to collisions with surrounding fluid molecules. In this way, a motor protein is like a car moving through a crowded city in the middle of a hurricane.
In this talk, David Altman will discuss how a cell’s miniscule engines achieve this remarkable feat. He will highlight his own research studying the behavior of a type of molecular motor called myosin, which is most notable for being the biomolecule responsible for muscle contraction.
David started his research career as an undergraduate at the University of Chicago, where he studied how microscopic particles in solution move near a boundary. He earned his Ph.D. in Physics from Stanford University, conducting research in a biochemistry lab that introduced him to the motor protein myosin. He then conducted two post-doctoral fellowships in the Department of Chemistry and in the Department of Chemical Engineering at Stanford. He is currently an Associate Professor of Physics at Willamette University, where his research lab uses techniques and approaches from multiple disciplines to understand how myosin motors function and are regulated in a cell. David also enjoys fiber arts, and is currently knitting plush models of the amino acids, the building blocks for proteins.
