Very sad news, John Gurdon has died.

A developmental biologist's developmental biologist, Nobel prize winner

His work is the foundation of much of today's dev & stem cell bio.

An inspiration to many, including me. Always asking questions & wanting the answers

It was a lot of fun and a tremendous synergy of intents dear @rezamehdipour.bsky.social! Thank you

We discovered that the SUN5-Nesprin3 LINC complex forms a hexagonal lattice at the sperm HTCA, which radically reshapes the nuclear membrane locally!
Our findings also provide the structural basis for understanding the severe ASS (Acephalic Sperm Syndrome) male infertility phenotype.

“The Website” is here! It can be intimidating getting into analysis of #CryoET data, and software is evolving all the time👩‍💻🚀. @phaips.vd.st & @florentwaltz.bsky.social put our lab’s workflows into an online guide. We hope this helps lower the bar to joining #TeamTomo. Feedback much appreciated! 🧪🧶🧬🔬

Hey #TeamTomo,
Ever been in need of a tutorial about the fundamentals of cryo-electron tomography? From preprocessing raw frames to high-res subtomogram averaging?
That's why @florentwaltz.bsky.social and I made this website!

Finally in peer-reviewed form: Mapping the ultrastructural topology of the corynebacterial cell surface. @bupbuse.bsky.social @vikramalva.bsky.social

The unique #CellEnvelope of #corynebacteria: @tbharat-lab.bsky.social &co map the C. glutamicum cell surface, revealing a patchy S-layer & specific assembly of the PS2 protein, thereby informing our understanding of cell envelopes that contain #MycolicAcids @plosbiology.org 🧪 plos.io/3Y6JNgw
Left: The atomic model of the PS2 lattice is shown in top and side views. PS2 hexamers are repeated in the 2D sheet with a lattice constant of 176 Å. Each PS2 monomer is colored and labeled separately within the hexamer, which repeats throughout the lattice (with pore dimensions highlighted). The side view of the lattice shows the smooth surface facing the extracellular space and rough surface with coiled-coil segments protruding towards the MM. Top right: Interactions at the hexameric and trimeric interfaces are stabilized by both hydrophilic and hydrophobic residues. Bottom right: A cell envelope tomogram was used to overlay the cryo-EM structure of the S-layer onto the in situ S-layer tomographic density. A single slice of the tomogram is shown, with the overlayed PS2 S-layer lattice in green and the tomogram in grayscale. The S-layer (surface layer), MM (mycomembrane), IM (inner membrane), and Cytosol are labeled.

Excited to share our new preprint on co-transcriptional splicing! U1 snRNP is recruited to RNA polymerase II through multiple interaction sites, with elongation factor SPT6 binding directly to the U1 snRNP protein.

science.org/doi/10.1126/... Just published! We uncovered a molecular machine that connects the cell's two major structural networks revealing how cells accomplish precise internal reorganization - a process disrupted in diseases ranging from cancer to multiple sclerosis.
Active microtubule-actin cross-talk mediated by a nesprin-2G–kinesin complex
Nesprin-2 Giant links the nucleus to the cytoskeleton, enabling actin transport and nuclear movement through kinesin-1 activation.
