Ancient co-option of LTR retrotransposons as yeast centromeres
The evolutionary origins of the genetic point centromere in the brewer's yeast Saccharomyces cerevisiae, a member of the order Saccharomycetales, are still unknown. Competing hypotheses suggest that t...

Absolutely thrilled to share the latest work from my lab focused on the variation and evolution of human centromeres among global populations! We assembled 2,110 human centromeres, identifying 226 new major haplotypes and 1,870 α-satellite HOR variants. www.biorxiv.org/content/10.6...

Fellow yeast enthusiasts, does anyone have the genomic or amino-acid substitution for the cdc20-1 ts mutant - thanks!

Very cool to see Jana’s epic on point centromere evolution published. Congratulations to all!

Although, it makes one wonder how these strange centromeres evolved in the first place?
How do new centromeres evolve while staying compatible with the division machinery?

Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore.

1/ 🐶💤

In Tony Hyman–style LLPS land:

Scaffold = the dog bed

Clients = extra dogs + toys that hop on

Rule of the game:

The bed decides where the nap-pile forms.
Other dogs can jump on, but somehow they don’t change how the bed behaves.
Oh wow! I wish someone can explain it to me "like a child or a Golden Retriever" (paraphrasing Margin Call).

Happy to share our latest preprint.

We uncover a previously uncharacterised and evolutionarily conserved chromatin architecture in premeiotic gonadal germ cells, revealed through integrated cytological and high-resolution Hi-C approaches.

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.

Condensin I and II promote the drastic spatial rearrangement of the human genome upon mitotic entry. While condensin II is known to initiate this proc…

This is a good time to remember that Moas, Emus, and the other ratites diverged so long ago, they FLEW to different continents, and then lost the ability to fly and became giants independently. You can't just sprinkle a few variants to make one into the other.
