WebJun 24, 2024 · Abstract. Bending of cilia and flagella occurs when axonemal dynein molecules on one side of the axoneme produce force and move toward the microtubule (MT) minus end. These dyneins are then pulled back when the axoneme bends in the other direction, meaning oscillatory back and forth movement of dynein during repetitive … WebDynein moves toward the minus end of the microtubule, which in axons is oriented toward the cell body. ... Most kinesins move towards the MT plus end, whereas dynein moves in the opposite direction. Therefore, kinesins are thought to be responsible for anterograde transport (Griffin and Watson, 1988), and dynein for retrograde MT-based ...
