@attychang.bsky.social, @nanigrotjahn.bsky.social et al. show that cytoplasmic #ribosomes on #mitochondria alter the local membrane environment for protein import. rupress.org/jcb/article/... 📕 From The Year In Cell Biology: rupress.org/jcb/collecti... #CellBio2025
Many spores from the Firmicutes group are decorated with hair-like structures. Since the 60s, they remained a mystery. @remaut-lab.bsky.social named these fibres ENdospore Appendages (ENAs). Using Cryo-ID, we report the identity, structure and function of F-ENA. www.nature.com/articles/s41...
Cryo-EM identifies F-ENA of Bacillus thuringiensis as a widespread family of endospore appendages across Firmicutes - Nature Communications
B. thuringiensis spores contain uncharacterized protein filaments that extend from the surface of the exosporium. Here, the authors show that these filaments feature conserved β-barrel neck domains an...

This paper advances deep proteome sequencing, improving detection of protein variants & isoforms beyond standard shotgun proteomics. By analyzing six human cell lines, it identifies a million unique peptides from 17,717 protein groups, highlighting translation of most alternatively spliced isoforms.

Lauren Bird@laurenbird.bsky.social · last yr.Excited to share this story from my PhD, out today in Nature Communications! We show that Coxiella removes cathepsin B to reduce lysosomal hostility and promote bacterial success. This depends on a vacuole established by effector CvpB. www.nature.com/articles/s41...
