New #cryo-EM #preprint- 'Structural mechanisms of drebrin-mediated F-actin network modulation'. Weilong impressively classified out two small #actin binding domains competing for the same surface on #F-actin, one of which also exists in two conformations! #drebrin www.biorxiv.org/content/10.6...

SPIN90 and #YanCao strike again! First NPF to only activate a subset of Arp2/3 iso-complexes to regulate lamellipodial actin & protrusion efficiency. Great collaboration with @romet-jegou-lab.bsky.social #ManosMavrakis polarized fluorescence microscopy rocks 🤘💥🎉 www.biorxiv.org/content/10.6...

Now for something completely different - Way lab does immunology - check out our @science.org paper - Branched actin networks mediate macrophage-dependent host-microbiota homeostasis. The work was driven by the 2 first authors @luiz90vasc.bsky.social @shainahuang.bsky.social

Our paper on Arp2/3-mediated bidirectional actin assembly is out @natsmb.nature.com 🚀 After great reviews & community feedback, this version includes new insights beyond the preprint:) Huge thanks to all co-authors!!! @drmichaelway.bsky.social @romet-jegou-lab.bsky.social @carolynmoores1.bsky.social

Another wonderful collaboration with @alanbrownhms.bsky.social lab 👇 Zhang lab (co-first author @qingweiniu.bsky.social) contribute the doublet structure from Crithidia fasciculata, a model organism that infects mosquitoes.

Excited to announce the 10th "Choanoflagellates & Friends Workshop" over May 20-22 in our own Institut Pasteur in Paris: 2025choanocon.wordpress.com Registrations open til March 15, abstract til March 5. Pre-conference event for students/postdocs on 19/05. Plenty of slots for selected talks/posters!

Working on actin cytoskeleton and Arp2/3 complex? Check out our latest work～https://www.biorxiv.org/content/10.1101/2025.01.31.635869v1 In this work, we found SPIN90 forms a dimer, facilitating bidirectional actin filament nucleation by activating two Arp2/3 complex #Cryo-EM #Actin #Arp2/3
