The Qiu biophysics group discovered a biological motor that travels in different directions depending on context. The animations shows how a KlpA motor protein (blue) moves in one direction when it is bound to a single microtubule track (green). However, when a KlpA motor protein is bound to two different microtubules (green and red), it moves in the opposite direction. Their discovery is reported in Nature Communications.
