Sensory cilia: How molecular motors can shape ciliary tip organization and diversity

In this issue, Wang et al. (https://doi.org/10.1083/jcb.202412213) reveal the specific contribution of the Kif19A kinesin motor to the shaping of the ciliary endings of Drosophila mechanosensory organs. They also explain, using mathematical modeling, how a combination of directed transport by this motor, free diffusion, and local binding of molecules can organize molecular domains at the ciliary endings.
