Excited to share our new paper! We developed a method to visualize proteasomal degradation at the single–molecule level in live cells, enabling us to dissect distinct modes of substrate engagement, probe co-factor dependence, and study proteasome–ribosome collisions. www.biorxiv.org/content/10.6...

Out now in Cell Systems: We develop a technique to visualize influenza A virus in live cells with single viral RNA resolution. Combined with precise readouts of viral transcription, we map the whole influenza A viral life cycle and identify key bottlenecks in infection. www.cell.com/cell-systems...

How does a scanning ribosome decide where to start protein synthesis? In our new bioRxiv preprint, we identify an extended translation initiation sequence, the eTIS, an ~80-nt region around the start codon that shapes initiation efficiency: www.biorxiv.org/content/10.6... #Ribosome #CryoEM #mRNA

Happy to share our preprint! Using massively parallel reporter assays, single-molecule imaging, deep learning and cryo-EM, we decode the sequence requirements for translation initiation and describe the “extended translation initiation sequence” (eTIS) that modulates start codon recognition. 🧵👇

And it's out! I'm thrilled to share our new paper (Adriaenssens et al., Nat Cell Biol 2025). This paper describes a new mechanism for the initiation of autophagosome biogenesis. We found that this WIPI-ATG13-driven pathway is preferentially used by a group of transmembrane autophagy receptors.

How do mitochondrial ribosomes keep pace with membrane insertion? Now out in NSMB: We show that mitoribosomes slow down at defined positions linked to membrane insertion and protein topology: rdcu.be/fhqIT #Mitochondria #Ribosome #CryoEM
