Providing order amongst constant traffic: #LMBResearch from Sean Munro (@cellbiol-mrclmb.bsky.social) with John Briggs (@mpibiochem.bsky.social) reveals how GOLPH3 allows COPI vesicles to distinguish between Golgi residents & ER-bound proteins. Read more: www2.mrc-lmb.cam.ac.uk/protein-sort...

The mechanistic basis of cargo selection during Golgi maturation. From Rebecca Taylor, @katciazynska.bsky.social, @jggkaufman.bsky.social & @grigorytagiltsev.bsky.social at @mpibiochem.bsky.social with David Owen and Sean Munro's group @cellbiol-mrclmb.bsky.social | www.science.org/doi/10.1126/...

The mechanistic basis of cargo selection during Golgi maturation
Resident proteins of the Golgi recycle in vesicles and the protein GOLPH3 enables the COPI vesicle coat to accomplish this.

How did a brain gene end up behaving like a virus? Research has shown that there is an evolutionary connection between Arc, retroviruses, and virus-like genetic elements called retrotransposons. More at Molecule of the Month: pdb101.rcsb.org/motm...
A comparison of the structures of dArc1 (capsid: 6TAP; pentamer: 6TAR), the retrovirus HIV (capsid: 3J3Q; pentamer: 7URN), and the retrotransposon Ty3 (6R24). Pentamers are shown in orange, and hexamers in yellow in the upper panel. In the lower panel, pentamers are shown with monomers colored in different shades of orange.

We’ve uncovered Asgard chromatin structures formed by a Hodarchaeal histone : closed hypernucleosome conserved in archaea and an open form resembling the H3-H4 eukaryotic octasome. Fantastic work by @harshranawat.bsky.social! www.biorxiv.org/content/10.1... #Chromatin #Asgard #Archaea #cryoEM

Thrilled to share these experiments on shaping focused ion beams to explore different ways of milling. Here, we explore using different beam geometries to generate cellular thin sections/lamellae. The video shows elongating the beam on a charging spot burn www.biorxiv.org/content/10.1...

Mature #HIV-1 contains >2000 copies of “spacer peptide 2”, but we didn’t know why. We now see that SP2 binds the matrix protein and triggers the change into its mature arrangement. Summary video from @margotriggi.bsky.social
