A Protein that Makes You Do the Twist (VIDEO) CNRS This video is under embargo. Please login to access this video. Caption This video shows the movement of a normal larva (left) and a larva expressing Myosin 1D in its normally symmetrical epidermis. Whereas the normal larva crawls linearly, with its ventral side in contact with the liquid, the modified larva is twisted and moves via directional 'barrel rolls.'
