I am pleased to share a new preprint from my postdoc in the @dseruggia.bsky.social lab. We discovered a structural dependency within the CORE module of the transcriptional coactivator SAGA, which regulates the stability of its histone acetyl transferase, KAT2A.

Disruption of the SAGA CORE triggers collateral degradation of KAT2A
The SAGA transcriptional co-activator complex regulates gene expression through histone acetylation at promoters, mediated by its histone acetyl transferase, KAT2A. While its structure and function ha...

1/ New preprint alert!
In collaboration between the Rosen, Redding, Collepardo-Guevara & Gerlich labs, we uncover a surprising principle of chromosome organisation: electrostatic repulsion positions centromeres at the chromosome surface during mitosis.

An electrostatic repulsion model of centromere organisation
During cell division, chromosomes reorganise into compact bodies in which centromeres localise precisely at the chromatin surface to enable kinetochore-microtubule interactions essential for genome se...

We found a new asymmetry in the large-scale chromosome structure: sister chromatids are systematically shifted by hundreds of kb in the 5′→3′ direction of their inherited strands! The work was led by Flavia Corsi, in close collaboration with the Daniel Gerlich lab.
