Myosin

I believe a crucial aspect for undergraduates wanting to pursue higher education include research. I have been involved in extensive research at my university in which we are focused on elucidating molecular mechanisms to improve basic understanding of muscle function and develop more effective treatments for diseases related to fatigue. The force generating capacity of muscle is ultimately derived from changes of muscles molecular motor, myosin. In that case, the lab that I am involved in closely investigates myosin and the mechanics and kinetics of myosin function. We hope these lines of investigation will both improve our basic understanding of muscle function and reveal the root molecular causes of related diseases, ultimately leading to improved treatments.Different techniques that are used include both in vitro motility assay and single molecular laser trap assays. The single molecular trap assay consists of an actin filament attached to two glass beads held in optical traps which are brought in to contact with a third bead sparsely coated with myosin.
