EMBL scientists have new detailed info about Asgard archaea DNA structures offering important clues to more complex cell evolution.

With #cryoEM, scientists found both open and closed chomatin structures with a possible role in regulating chromatin.

We just chose an Asgard with good genome completeness, encoding several histones ☺️ It’s been a while since we chose it for this project πŸ‘΅πŸ»πŸ˜Š

Lab’s first paper is out!! We show the first structures of #Asgard #chromatin by #cryo-EM πŸ§¬β„οΈ
Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...

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.

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.

🚨 Imagine a bacterium that refuses to follow the textbook:
It grows as tangled filaments, divides unevenly, reshapes its own membranes… and even builds grappling hooks.
Meet Litorilinea aerophila β€” and here’s why it blew our minds.

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!

Returning from a great visit to the Dodonova lab at EMBL to discuss archaeal histones and hypernucleosomes. Nice also to see a tribute to the hypernucleosome on EMBL premises !#Archaeasky
