The small #GTPase Rab1 is a master regulator of #Golgi traffic and #autophagy. van Vliet, Munro et al. @mrclmb.bsky.social performed a proteomic screen to identify novel Rab1 effectors, including a #dynein motor adaptor and cargo receptors for autophagy. rupress.org/jcb/article/...

Disordered linker of Kank1 forms rigid protein rod upon binding to 15 LC8 molecules and bridge the gap between membrane and microtubule.
New collaborative preprint!
A striking result: a disordered linker in KANK1 binds as many as 15 LC8 dimers, forming a protein rod that bridges cell membranes and microtubules!

Final version is out! Our large-scale cryo-ET dataset 🔬 of Chlamydomonas reinhardtii 🦠 is now published in @cp-molcell.bsky.social
Huge collaborative effort! So glad to see the community already using it to develop new resources & tools.

Dynein-2 prefers to bind the retrograde-targeted A-tubule in intraflagellar transport - likely because of its tyrosination, suggest cryo-ET data and MD simulations by @ichikawa-lab.bsky.social and coworkers

Our paper on dynein-2's track recognition mechanism is now published in The EMBO Journal @embojournal.org!!

Our special issue on ‘Cilia and Flagella’ is now out! Huge thanks to all (authors + reviewers) who contributed, and to our wonderful Guest Editors (@cilialab.bsky.social + @lottepedersen.bsky.social) for pulling it together.
Happy reading!

📣 Here it is — our overview on ciliary proteomics! Great discussions and writing with @mick-lab.bsky.social and Ronald Roepman 🙏🙏
Hope we didn’t miss anything important - apologies if we did!

Miao Gui and I wrote a Review for the @jcellsci.bsky.social special issue “Cilia and Flagella: From Basic Biology to Disease”. It provides a comprehensive and up-to-date overview of MIP structure, function, and the latest tools used to study them, crafted to serve both newcomers and experts.
Ever wondered what microtubule inner proteins (MIPs) are and what they actually do? Or perhaps you already know about them, but find it hard to keep track of which ones are conserved across species and how they support ciliary structure and function?

A milestone reached! 1000 citations on Google Scholar!
I am happy our recent study on the human sperm head-tail junction is now online. We find that SUN5 form an hexagonal lattice at the nuclear membrane, rationalising how mutations in SUN5 lead to infertility. Great work of @cryonas.bsky.social !

Happy to share our lab's recent #cryoEM studies that show how a SPIN90 dimer activates Arp2/3 complex to form either uni or bidirectional actin filaments. Congrats🎉👏 @justusfrancis.bsky.social @achyutha-kp.bsky.social @tejashyamk.bsky.social @sridharskulkarni.bsky.social @kiranvyshnav.bsky.social
Excited to share our latest work with @simonbullock11.bsky.social! We looked at how diverse mRNAs get selected for subcellular localization and it turns out that a single protein can recognize different RNA elements using shared features that weren’t apparent before.

Thrilled to see our study on how kinesin-2 motors are switched on and off published in @natsmb.nature.com ⚛️

Congrats to all authors from me and Anthony 🎉 @dunnschool.bsky.social Check out this animation made by talented PhD student @matthew-batisio.bsky.social 😆
Cryo-EM and biochemical reconstitution analysis reveal that Nde1 enhances Lis1 binding to autoinhibited dynein, promoting formation of a Phi-like-Lis1 intermediate during dynein activation

If you’d like to join me on this journey, NBME is hiring!! This is a fantastically rewarding career that keeps you very much in science. springernature.wd3.myworkdayjobs.com/SpringerNatu...
Nature Methods is also hiring to replace me (applications close August 4th!!!) and I will do everything I can to support their next bioimaging editor (ask me anything!). springernature.wd3.myworkdayjobs.com/SpringerNatu...
Congratulations!!! 🎉🎉🎉
🚨Last call to submit to the Forces in Cell Biology collection with @natcomms.nature.com and Scientific Reports! Deadline: 24th July

Come work at Nature Methods! A dream job. I know from experience 😄
New preprint from the lab - the first paper made (almost) entirely here @qmul.bsky.social
We report how human outer kinetochore complexes Ndc80 and Ska form cooperative oligomers, that together stabilise microtubule ends against shortening.

Latest preprint from the lab, many years in the making!
By combining #cryoEM with #AlphaFold3 modelling, we propose that norovirus NS3 forms a transmembrane RNA translocase.
This could have big implications for our understanding of viral replication & assembly (🧵)

Daniel's paper is now published in @jcellsci.bsky.social, great experience with @reviewcommons.org 😀
