Molecular design principles for bipolar spindle organization by two opposing motors | PNAS
During cell division in animal cells, a bipolar spindle assembles to segregate the
chromosomes. Various motor proteins with different properties ar...
π¨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? π€

Hydrolysis-deficient mosaic microtubules as faithful mimics of the GTP cap
Nature Communications - EstΓ©vez Gallego et al. present a study demonstrating that mosaic microtubules consisting of a mix of GTP hydrolysis-deficient tubulin mutants are faithful microtubule...
We're on a roll!π
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! π

The Stonewall Inn and The Stonewall Inn Gives Back Initiative are outraged and appalled by the recent removal of the word 'transgender' from the Stonewall National Monument page on the National Park Service website. This blatant act of erasure not only distorts the truth of our history, but it also dishonors the immense contributions of transgender individuals - especially transgender women of color - who were at the forefront of the Stonewall Riots and the broader fight for LGBTQ+ rights.
SIGBI followed by a next arrow

The Stonewall Inn released a response to the National Parks Service removing the word transgender from the park outside of the Inn. A great reminder that we have to look after each other

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

NuMA (green) also protects minus ends after uncapping/treadmilling by KIF2A/spastin. Really interested to see what happens structurally at these minus ends
