Which of the following proteins serves as the molecular motor that generates the sliding force between microtubule doublets in cilia?
Show answer and explanation
Correct answer: Ciliary dynein
Ciliary dynein forms inner and outer arms that extend from one microtubule doublet toward the next. It uses ATP hydrolysis to 'walk' along the adjacent doublet, creating the sliding motion that results in a ciliary beat.
