First first-author paper out! 🎉

We show that the classically repressive mark H3K27me3 can be linked to active transcription through a newly identified reader complex 🤯

Really grateful to everyone involved in this project during my PhD!

Using #SingleMolecule imaging we find that TFs:

-boost co-transcriptional #ribosomal #RNA processing!

-their binding #dynamics fundamentally differ for mRNA (transient) versus rRNA #transcription (stable)!

Proud to share the yeast telomerase structure, led by the talented @hongmiaohu.bsky.social in collaboration with the Wellinger and Chartrand labs. Discovered 37 years ago and took us nearly 7 years but totally worth the wait 😍.

Sequence-specific RNA recognition drives Restrictor-mediated termination of extragenic transcription Polizzese et al. show that the C3H1 zinc fingers (ZNFs) of ZC3H4 confer sequence-specific RNA binding to Restrictor. These ZNFs recognize a degenerate A/UGUA motif at ncRNA 5′ ends and are required for termination, whereas tethering of Restrictor to early elongating RNA Pol II depends instead on WDR82.

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.

A role for human senataxin in contending with pausing and backtracking during transcript elongation Han et al. use biochemistry and acute depletion of senataxin to reveal a role in RNAPII transcript elongation via reversal of pausing and backtracking. By contrast, senataxin has little direct effect on transcription termination.

A mechanism of synergistic Mediator recruitment in RNA polymerase II transcription activation revealed by single-molecule fluorescence Single-molecule fluorescence microscopy studies by Zhou et al. show that transcription activator proteins bind at UAS/enhancer DNA and then sequentially or simultaneously recruit Mediator coactivator and RNA polymerase II to form an initiation complex precursor. Multiple DNA-bound activators synergistically enhance recruitment by binding to the same Mediator complex.
