We are pleased to congratulate Jana Elsässer on the successful defense of her doctoral thesis at the University of Freiburg! Jana conducted her research as part of project B10 under the supervision of SFB 1381 PI Claudine Kraft. @biologyunifreiburg.bsky.social @kraftlabfr.bsky.social

Thanks to @cibss.bsky.social for recognizing Mariya, Riccardo and Hector from the lab with the CIBSS Award 2026, for our recent publication! Glad to be part of such a collaborative research environment. 📄: www.nature.com/articles/s41...

First ERC Synergy meeting with @martenslab.bsky.social and @jimhurley.bsky.social in Vienna, great start! Thanks Sascha for hosting 🙏 @erc.europa.eu

#JobAlert The @biologyunifreiburg.bsky.social of @uni-freiburg.de invites applications for a Professorship (W3) for Plant Biotechnology. ❗Application Deadline: 10 July 2026 🔗https://kurzlinks.de/1iyt #SignalsOfLife #PlantScience #CIBSS

Last week to submit your abstract to the Swiss Autophagy Conference 2026 (3-4 Sept, Fribourg)! A dynamic meeting for PhDs, postdocs & early-career researchers to present, learn & connect. Theme: Autophagy in Development, Disease & Ageing. 📝 Abstracts: 21 June: meetings.ls2.ch/autophagy-2026

Safe to say that Day 1 of 'Cellular mechanisms driven by phase separation' has been a success so far, with lots of great talks, including a keynote by Karla Neugebauer, and plenty of opportunities to socialise and get to know each other 🙌🏼 #EESPhaseSeparation @embo.org @embl.org

New preprint! Cell division has to happen at the right place but how Archaea pick that place is unknown. We now identified a three-protein system, Dip, that positions the divisome at midcell in H. volcanii and is broadly conserved across Archaea. A thread 🧵 www.biorxiv.org/content/10.6...

Two of our lab members are at the EMBO | EMBL Symposium on cellular mechanisms driven by phase separation this week! 🙌 Come and visit their posters: 📌 Mariya → Poster #114 📌 Joachim → Poster #54 #EESPhaseSeparation @events.embl.org @embo.org @embl.org

A new preprint from the lab showing how Atg1 regulates the BLTP Atg2. This study was spearheaded by Sonja Achleitner and Susanna Tulli, involving a fantastic collaboration with @ainaraclaveras.bsky.social and Gerhard Hummer. @maxperutzlabs.ac.at @viennabiocenter.bsky.social @maxplanck.bsky.social

Our ULK1–MTFR1L paper is now officially in @jcellsci.bsky.social, a good moment to reshare it. 🎉 The work identifies MTFR1L as a key coordinator of mitochondrial fission, mitophagy initiation and apoptosis. 👉 Paper: doi.org/10.1242/jcs....

A ULK1–MTFR1L feedback loop links mitochondrial fission, mitophagy and apoptosis

Summary: MTFR1L acts at mitochondrial mitophagy initiation sites, linking mitochondrial fission with autophagy by interacting with ULK1, regulating ATG13 stability, and forming a feedback loop that su...

🚨 Paper Alert! In this new work published in @jcellsci.bsky.social we shift our focus on MTFR1L and the feedback loop linking mitochondrial fission, mitophagy and apoptosis. MTFR1L emerges as a critical coordinator of the fission and autophagy machinery. 🔗Find the paper here: doi.org/10.1242/jcs....

New pre-print from the lab! We show that the subtilase SBT12a is essential for symbiosome stabilization in Medicago. Using HUNTER proteomics, we even got some of its substrates. Have a look. www.biorxiv.org/content/10.6...

What a blast! 🎉 Our International Symposium last week gathered 27 world class speakers and over 200 participants. From electrifying plenary talks to vibrant poster session chats, the energy was palpable and the atmosphere truly unforgettable. A massive thank you to all speakers and attendees!

That's a wrap on the 2nd International Symposium organized by @sfb1381.bsky.social in Freiburg! 🎉 Three days of great talks, fascinating science, and wonderful people. Loved being part of it. Huge thanks for the organisation!
