How do cells assess mtDNA quality?

Local ATP and membrane-potential gradients reflect mtDNA integrity and drive intracellular purifying selection.

We introduce FAST, a scalable mtDNA QC assay in S. cerevisiae.

Great collaboration with the Schmoller Lab.

Oxidative phosphorylation complexes contain subunits encoded by both the nuclear and mitochondrial genomes. How do cells coordinate the synthesis and assembly of these complexes at the inner membrane? We teamed up with Martin Ott (@mitolab.bsky.social) to address this in two recent papers.

Our study on the molecular function of translational activators for mitochondrial protein synthesis is published:

📢 Publication Alert: We're excited to share a new study from the Langer Lab published in @nature.com! It uncovers how an excess of RNA building blocks can destabilize mitochondrial DNA, which plays a role in age-related inflammation.

Our new pre-print from the Greenberg and Churchman labs shows that activity-dependent modulation of RNA stability is a major, and underappreciated, mechanism of gene regulation in neurons. Tutorial below! www.biorxiv.org/content/10.1... (1/11)

In a new study by our @pelleeas.bsky.social, we reveal how Mrx4 organizes translational regulation of cytochrome b synthesis at the mitoribosomal tunnel exit. Thanks @kawresearch.bsky.social for funding and @stirlingchurchman.bsky.social for the fun collaboration! academic.oup.com/nar/article/...

We just returned from a great retreat with the @osman-lab.bsky.social in the Austrian alps. Intensive scientific discussions on mitochondrial gene expression, fun people, delicious food and great scenery, thank you so much everyone!

New paper out from the Falkenberg and Gustafsson labs. Thanks to Pretzel for a successful collaboration.

The final version of our work on the in-cell architecture of the mitochondrial respiratory chain is now online in @science.org 🎉
You can find the full story here www.science.org/doi/10.1126/...
@verenaresch.bsky.social did a wonderful job on the cover and animation, she really brought it to life 👩‍🎨

We're on the cover of @science.org this week. Awesome work by @florentwaltz.bsky.social. #CryoET is reaching crazy resolutions inside cells, and this is just the beginning. Fantastic interpretation of the proton motive force by @verenaresch.bsky.social. Always a pleasure making #SciArt with you!🧪🧶🧬🌾

Less than a week left to apply to the open post doc position in our lab. Join us in beautiful Gothenburg to work on an exciting project!
