Microtubule-binding-induced allostery triggers LIS1 dissociation from dynein prior to cargo transport

WD Ton, Y Wang, P Chai… - Nature structural & …, 2023 - nature.com
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

Q Rao, L Han, Y Wang, P Chai, Y Kuo… - Nature structural & …, 2021 - nature.com
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 …

Structures of a mobile intron retroelement poised to attack its structured DNA target

K Chung, L Xu, P Chai, J Peng, SC Devarkar, AM Pyle - Science, 2022 - science.org
Group II introns are ribozymes that catalyze their self-excision and function as retroelements
that invade DNA. As retrotransposons, group II introns form ribonucleoprotein (RNP) …

[HTML][HTML] Cryo-EM structure of an active central apparatus

L Han, Q Rao, R Yang, Y Wang, P Chai… - Nature structural & …, 2022 - nature.com
Accurately regulated ciliary beating in time and space is critical for diverse cellular activities,
which impact the survival and development of nearly all eukaryotic species. An essential …

Abl2 repairs microtubules and phase separates with tubulin to promote microtubule nucleation

D Duan, W Lyu, P Chai, S Ma, K Wu, C Wu, Y Xiong… - Current Biology, 2023 - cell.com
Abl family kinases are evolutionarily conserved regulators of cell migration and morphogenesis.
Genetic experiments in Drosophila suggest that Abl family kinases interact functionally …

LRRC23 truncation impairs radial spoke 3 head assembly and sperm motility underlying male infertility

JY Hwang, P Chai, S Nawaz, J Choi, F Lopez-Giraldez… - Elife, 2023 - elifesciences.org
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. …

[HTML][HTML] Multi-curve fitting and tubulin-lattice signal removal for structure determination of large microtubule-based motors

P Chai, Q Rao, K Zhang - Journal of structural biology, 2022 - Elsevier
Revealing high-resolution structures of microtubule-associated proteins (MAPs) is critical for
understanding their fundamental roles in various cellular activities, such as cell motility and …

Microtubule binding-induced allostery promotes LIS1 dissociation from dynein prior to cargo transport

WD Ton, Y Wang, P Chai, C Beauchamp-Perez… - Biorxiv, 2022 - biorxiv.org
The lissencephaly-related protein LIS1 is a critical regulator of cytoplasmic dynein that
governs motor function and intracellular localization (e.g., to microtubule plus-ends). Although …

LRRC23 loss-of-function impairs radial spoke 3 head assembly and causes defective sperm motility underlying male infertility

JY Hwang, P Chai, S Nawaz, J Choi, F Lopez-Giraldez… - bioRxiv, 2023 - biorxiv.org
Radial spokes (RSs) are T-shaped multiprotein complexes in the 9+2 axoneme of motile cilia
and flagella that couple the central pair to the peripheral doublet microtubules. RS1, RS2, …

[PDF][PDF] Cryo-EM structures of outer-arm dynein array bound to microtubule doublet reveal a mechanism for motor coordination

Q Rao, Y Wang, P Chai, YW Kuo, L Han, R Yang… - Biorxiv, 2020 - scholar.archive.org
Thousands of outer-arm dyneins (OADs) are arrayed in the axoneme to drive a rhythmic
ciliary beat. Using electron microscopy, we determined the structure of OAD array bound to …
