The Wilkinson Lab is open for science! @mskcancercenter.bsky.social

🧬We'll be finding funky new RNA biology, mainly by looking at reverse transcriptases (i.e. the Best Enzymes In The World)🧬

annnd: I'm hiring - come join! Especially postdocs and PhD students - please get in touch (NYC is great)

This one is a bit of a departure from the usual and definitely a work in progress!

We found that by using ab initio reconstruction at very high res, in very small steps, we could crack some small structures that had eluded us - e.g. 39kDa iPKAc (EMPIAR-10252), below.

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.

Great to see our story on dynein & kinesin co-dependence published www.nature.com/articles/s41..., and absolutely chuffed that it's made the front cover (thanks NSMB!). A brilliant News & Views too by Steven Markus www.nature.com/articles/s41.... Collab between @carter-lab.bsky.social & Straube lab🔬

Happy to have contributed a small part to this exciting story about the ancestors of eukaryotic tubulin in Asgard archaea. Congratulations to all the co-authors!
Asgard archaea have actin - but what about microtubules? Where do they come from? 🧐 Our new paper www.cell.com/cell/fulltex... by @xujwet.bsky.social & @florianwollweber.bsky.social, in collaboration with the Schleper & Wieczorek labs, describes tiny Asgard microtubules! #TeamTomo #ArchaeaSky 1/6

How do great discoveries sometimes come from unexpected findings? It’s right there in the first paragraph of Fleming’s paper: a contaminated plate led to the discovery of penicillin.

Much work was required to turn the discovery into practice, but this simple observation started it all.

If you’re interested in how molecular motors coordinate to power intracellular trafficking events (e.g. endocytosis), I’ve got a PhD position available to study this at vibrant Bristol uni. In this project, we will capture highly dynamic events by #cryoEM, single molecule imaging & cell biology. 🔬❄️🧪

Our review of Intraflagellar transport is out now! We cover lots of the recent advances in our understanding of IFT, and where we think there are still some gaps.

Intraflagellar transport (IFT) ensures delivery of selected proteins into cilia. The IFT protein complexes IFT-A and IFT-B polymerize at the base of the cilium to form an anterograde train that facili...
