Microtubules (VIDEO)

Penn State

Caption

This is a movie of a polymerizing microtubule (originating in bottom left corner) encountering a static microtubule in middle of screen. During the encounter the polymerizing microtubule is bent by a fluorescently-labeled complex of end-binding protein 1 (EB1) and a kinesin motor. After being bent, the microtubule eventually snaps back to its original position and the EB1-kinesin complex continues to walk along the static microtubule. Time (in seconds) is shown at top right and scale bar is 1 micron.
