Here we are! To celebrate our arrival, here is a #trypanosome expanded ~13 times & stained for tubulin, individual cortical #microtubules can be recognised, what was only achievable by EM before.

Paper by the Schneider lab( @schneian.bsky.social ) & collaborators w/co-first authors Corinne von Känel & Salome Aeschlimann "TbTim20 facilitates protein import at a low membrane potential in trypanosomes lacking the mitochondrial genome" @febsj.bsky.social nccr-rna-and-disease.ch/news/article...

Multiple so called "quality control checks" by the journal almost killed us. - But now it is out!
A novel mito. protein import factor is only essential in T. brucei without kDNA. – Check it out.
Congrats, to the first authors Corinne and Salome and to all our coauthors.

Protein import into mitochondria relies on TIM complexes and the membrane potential. Trypanosoma brucei has a unique TIM complex, and the role of one subunit, TbTim20, has remained unclear. Here, we ...

The trypanosomal TAC is required for mitochondrial DNA segregation. We provide insight into TAC assembly: one of the most extreme sorting event for any mitochondrion.
