In this special episode, Chris and Mike invite David Altman into the studio to discuss his research into different forms of a protein called myosin. In cells, there are chains of molecules called actin that crisscross throughout the cell. Myosin is able to grab onto the actin and pull, causing different forms of work to happen. For instance, bundles of myosin are the cause for muscles to contract. In other examples, myosin can carry cargo through the cell. We will discuss these uses and also how David is able to study the properties of myosin.
