🚨New paper out @pnas.org!

Do you want to know how do mitotic motors organize the spindle? Wei Xiang's simulations show that just a plus & a minus motor are enough to drive bipolar spindle assembly. Could this explain why kinesin-5 & dynein evolved their unique properties? 🤔

that's hot!
Preprint alert! I’m publishing my last paper from my postdoc work on archaeal cell biology, with @mullinslab.bsky.social, @archaellum.bsky.social, @samjlord.bsky.social, @marleenvw.bsky.social, @arghya93.bsky.social, and more great folks (thread below with more details)

We're on a roll!🚀
Check our latest research @naturecomms.bsky.social: rdcu.be/ecXzr
We reveal how mosaic MTs faithfully mimic the GTP cap, highlighting lattice expansion (not pf twist) as the structural cornerstone of MT stability and dynamic instability.

Congrats to Juan and everybody involved! 🎉

New preprint out 🔥🔥 on my postdoc work with @manuelthery.bsky.social and @lblanchoin.bsky.social about how we can create sustained dynamic steady states of actin network inside microscopic wells that contract "forever" without collapsing! A thread 🧵

Solving 25 years of frustration, Daniel Abbühl managed to tag trypanosome tubulin and to express it in an inducible manner, hence revealing flagellum assembly! A tour-de-force!

Microtubule minus ends are dynein/dynactin cargo via direct interaction with NuMA!
So thrilled to share my first paper as a first author. In these in vitro reconstitutions we observe how purified #spindle #proteins interact with #microtubules using #TIRF #microscopy 🔬👩🏻‍🔬
Grateful to those magic brains of the @surreylab.bsky.social for all the support along the way! 🫂
New: Colombo et al. @surreylab.bsky.social show that NuMA is a mitotic dynein adaptor that binds and caps microtubule minus ends, explaining how dynein, NuMA, dynactin, and Lis1 focus microtubule minus ends at mitotic spindle poles https://buff.ly/41aj9F9

Centromere evolution isn't a sudden switch!

Our study shows centromere transitions are a step-by-step process driven by a combination of drift and selection. Discover how the kinetochore interface shapes this gradual change in our new preprint 🥳 doi.org/10.1101/2025.01.16.633479 🧵(1/8)

Mechanistic basis of temperature adaptation in microtubule dynamics across frog species
Despite tubulin’s evolutionary conservation, microtubule dynamics are highly temperature sensitive. Troman et al. use natural tubulin variants from closely related Xenopus species to show that a decrease in tubulin’s apparent activation energy and weakening of lateral lattice contacts stabilize microtubules in cold-adapted frogs.
