This video shows uniform distribution of kinesin-3 motors (fast motors that detach quickly under load) carrying a microtubule. Motor tethers are shown as red springs that are partially transparent until stretched beyond their 40 nm rest length. A portion of the microtubule (green) is shown; the plus end is at the left. Motor density was artificially chosen to be high (40 motors/μm) for better visualization. Microtubule diameter and height and kinesin tether are to scale, but motor heads and tail (yellow) are not. The frame rate is 20 fps. See the paper by Arpağ et al. in the October 21 issue of Biophysical Journal.
