Mechanical Transport by Molecular Motors:
how do we control traffic in cells?
how do we control traffic in cells?
Research focuss: team work by protein machines, as controlled by chemical energy, disease-relevant roadblock (tau), road condition (microtubule structural defect), and mechanical coupling between motors (lipid bilayers).
