Axonemal dyneins are tethered to doublet microtubules inside cilia to drive ciliary beating but the mechanisms regulating their localization and function are poorly understood. Here authors report a cryo-EM reconstruction of a three-headed axonemal dynein natively bound to doublet microtubules isolated from cilia which provides a framework to understand the roles of individual subunits.
