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

🚨 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 #preprint from CRN Team Hurley! The team uncovers the mechanism of ATG2A-mediated lipid transport 🧬 Structural modeling and simulations show that N-terminal helices gate lipid transfer, and a designed mutant transfers lipids three times faster in vitro. 🔗 bit.ly/4rHuWpr

Really happy to see this one out: www.sciencedirect.com/science/arti... Alibek's drive & great coll w/ friends @gekaragoz.bsky.social & E. Hallacli resulted in a cool story that starts with our beloved #Marchantia and ends with iPSC-derived neurons 🤩🤪 A short 🧵

Why do pathological protein aggregates persist in cells and how can we overcome this? In our new preprint, we show that Tau aggregates fail to initiate selective autophagy and that their autophagic degradation can be restored. #Autophagy #Tau #Proteostasis Out now 👇 www.biorxiv.org/content/10.6...

LLOMe has long been used to study lysosomal damage, yet how it works has remained a mystery. Using cryo-electron tomography, we show it forms amyloid structures inside lysosomes that mechanically rupture membranes – revealing a new paradigm for lysosomal failure. 🔗 doi.org/10.64898/202... #CryoET
