Our paper is now out in Nature:

“Ancient co-option of LTR retrotransposons as yeast centromeres”

www.nature.com/articles/s41...

A short thread on how retrotransposons helped give rise to yeast point centromeres.

What determines cell-cycle-dependent loading of human CENP-A?
Bypassing the MIS18α/β scaffold via artificial M18BP1 dimerization allows @andrea-musacchio.bsky.social and coworkers to identify determinants, including structure of the M18BP1 SANTA domain

Plasma cells are the immune system’s antibody factories, and they originate from B-cells.

Researchers from our Busslinger lab developed a new CRISPR screening method to find the genes that control this transition inside living mice:

Finally out! Check out our new work on how M18BP1, known so far to be important for the epigenetic maintenance of centromeres, supports chromosome condensation when the cell enters mitosis. We also uncover a regulatory ménage á trois between condensin II, M18BP1 and MCPH1.

We are diving into 2025 with how we finished 2024: with great research. The lab of Jan-Michael Peters discovered how #cohesin not only drives #chromatin architecture, but also links it to #epigenetics. Now in @embojournal.bsky.social:
