Microtubule-binding-induced allostery triggers LIS1 dissociation from dynein prior to cargo transport
The lissencephaly-related protein LIS1 is a critical regulator of cytoplasmic dynein that
governs motor function and intracellular localization (for example, to microtubule plus-ends). …

[HTML][HTML] Structures of outer-arm dynein array on microtubule doublet reveal a motor coordination mechanism
Thousands of outer-arm dyneins (OADs) are arrayed in the axoneme to drive a rhythmic ciliary
beat. Coordination among multiple OADs is essential for generating mechanical forces to …

LRRC23 truncation impairs radial spoke 3 head assembly and sperm motility underlying male infertility
Radial spokes (RS) are T-shaped multiprotein complexes on the axonemal microtubules.
Repeated RS1, RS2, and RS3 couple the central pair to modulate ciliary and flagellar motility. …
