🚨 New work from our lab: ESR1 fusions don’t just alter ER signalling — they fundamentally change how the protein behaves in the nucleus. We show they form chromatin-linked condensates that reshape nuclear organisation and transcription. www.biorxiv.org/content/10.6...

It was great working with students Kun and Ryan and @hannahlong.bsky.social, combing the literature to try and find examples of bona fide disease-causing variants in non-coding elements - promoters, enhancers and silencers. www.nature.com/articles/s41...

⚡Preprint alert⚡ So proud of @amohamed98.bsky.social! Abdallah determined the cryo-EM structure of BRD4 bound to the kinase P-TEFb, defining the molecular basis of this key transcription interaction — and revealing that BRD4 and AFF4 binding are mutually exclusive to P-TEFb. Lots more inside 👇

Finally out in @Cellcellpress! Proteins with long IDRs are prone to misfolding during protein synthesis. This is prevented by mRNA 3′UTRs that act as mRNA-based IDR chaperones. www.cell.com/cell/fulltex...

mRNA 3′ UTRs chaperone intrinsically disordered regions to control protein activity
Highly conserved mRNA 3′ UTRs act as co-translational chaperones for intrinsically disordered regions (IDRs), preventing inter-domain misfolding and enabling biogenesis of fully active proteins.

Happy 30th birthday to this paper published March 22, 1996, one of the studies that moved chromatin biology from correlation toward mechanism. Brownell et al. linked a transcription-associated Tetrahymena HAT to yeast Gcn5p, providing a biochemical link for chromatin modification to gene activation.
