Gigant/Ménétrey Lab

Paumier, Sauvanet, Gigant @mikicalab.bsky.social highlight work from Muñoz-Hernández, Xu et al @mike-wieczorek.bsky.social (rupress.org/jcb/article/...) which describes new insight into the means by which NEDD1 protein recruits the γ-TuRC to microtubule-organizing centers rupress.org/jcb/article/...

Benoit Gigant presented his latest results published in PNAS Nexus (10.1093/pnasnexus/pgae487) on the protein Tau and its interaction with microtubules at the 6th Journées du Réseau France Microtubules to be held in Toulouse on June 26 and 27, 2025.

#RésultatScientifique 🔎 Des chercheurs ont découvert que les protéines ARF, existaient bien avant l’émergence des cellules eucaryotes ! 🦠

Cette découverte éclaire l’évolution des mécanismes cellulaires et ouvre de nouvelles perspectives sur l’histoire du vivant !

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

The Arf Family GTPases are crucial eukaryotic proteins in organelle dynamics. Our paper shows their Asgard origins and the hallmark Arf mechanism of membrane-localization in these asgard proteins! Led by Cathy Jackson @ijmonod.bsky.social; with Marek Elias and @mikicalab.bsky.social.

Thank you Rémi!

Hi Rémi! Could you add us to the pack (if place still available😅)? Thanks.

Thank you!

Thanks Chloé!

Hi Olivier! Could you add us to the pack? Thanks.

Hi, can we join in?

We are thrilled to announce that our laboratory has officially moved to a brand new building as of early November! This new space will allow us to provide an even better environment for our team and collaborators.
