The first cut is the deepest: Cleavable signal peptides direct thousands of different nascent proteins to the endoplasmic reticulum. Oddly, SPs are all different and nevertheless cleaved with exquisite specificity. Our new cryo-EM structures + MD solve this paradox:

Very happy that NWO supports this major upgrade of our national EM infrastructure. It is great that this initiative got broad support all over NL, and it will EMPower fantastic science - looking forward to that!

Congratulations Marten! We hope this new version of pytom will be useful to many cryo-ET enthusiasts.
Exciting Bijvoet Seminar by Marie-Eve Aubin-Tam from @tudelft.bsky.social on the engineering of bioinspired and living materials!
Online today at @naturecomms.bsky.social and a great opportunity for our first post @bsky.app: in a major team effort, we reveal the structural mechanisms for centrosomal recruitment and organization of the human microtubule nucleator γ-TuRC: www.nature.com/articles/s41...
And now to something completely different: the response of an anaerobic archaeon to oxidative stress. Tubular nanocompartments encapsulate virus-like particles! Great work by Wenfei Song and many colleagues from @bijvoet-centre.bsky.social and @mib-wur.bsky.social.

In one of our first publications in 2025, with colleagues from St. Louis, Leiden and Boston, we shed light on the molecular mechanisms of motile cilia, structures used by cells to propel themselves through fluid or to move fluid across their surfaces. www.nature.com/articles/s41...
Signal peptides are highly variable, yet the signal peptidase complex processes them with remarkable specificity. Here, authors combine cryo-EM, molecular dynamics simulations and modeling to reveal a...

A major new national facility for electron microscopy, called EMPower, has been awarded to a consortium of Dutch universities and medical centers. EMPower aims to pave the way for major discoveries im...
The γ-TuRC plays a central role for nucleation of microtubules at the centrosome. Here, the authors dissect structural mechanisms for centrosomal recruitment and regulation of the γ-TuRC and identify ...
Reactive oxygen species (ROS) pose a significant threat to biological molecules, prompting organisms to develop systems that buffer oxidative stress and contain iron, which otherwise amplifies ROS pro...
Cryoelectron microscopy, cryoelectron tomography and proteomics are used to resolve the 96-nm modular repeat of axonemal doublet microtubules from both sperm flagella and epithelial cilia of the ovidu...

Final PhD paper now reviewed and published in JSB:X. I was happy with some great reviews that improved the paper! Thanks to Sander Roet for his help with the code base, and Remco Veltkamp and @fridof.bsky.social
I guess I should have posted a bit earlier, but I'm very excited that my #MSCA application got accepted! I'll be working at @fridof.bsky.social lab @utrechtuniversity.bsky.social to develop my #teamtomo skills on my project: Protein ER-ways! Here's to gaining new insights on ER protein biogenesis!
