Preprint alert! 🚨

We are very excited to share our new manuscript on Bohring-Opitz syndrome, a devastating rare monogenic disorder driven by truncating variants in ASXL1.

This project was led by PhD student Emma Doyle, one of the OG Conway lab members 💪. 1/6

Divergent Pathogenic PR-DUB Complex Variants Converge Functionally Via PRC2 Displacement From Chromatin
The PR-DUB complex is responsible for erasing the repressive histone modification, H2AK119ub1. ASXL1-3 proteins are mutually exclusive catalytic partners of BAP1 in the PR-DUB complex. Somatic heteroz...

How do cells tune PRC2 allostery? We find EZH2 Ser21-phos restrains PRC2 adoption of the compact active state. Loss of this restraint promotes H3K27me3, redistributes cPRC1, and impairs differentiation. New bioRxiv with @kasinath-lab.bsky.social & @garcialabms.bsky.social! tinyurl.com/4369kmh2

We’ve recently been awarded a MIRA R35 and an R01 to study non-canonical roles and missense mutations of the Polycomb system in health, cancer, and neurodevelopmental disorders. We are seeking an animal tech with lab manager duties. Please share!

🚨 We discovered a new mode of Hox gene regulation in annelids! 🪱 A distal enhancer acts as a "global control region", lifting Hox genes from Polycomb repression. This is reminiscent of Hox gene control in vertebrates, but the two modes likely evolved convergently.

Now out @natbiotech.nature.com ! Do lncRNAs commonly bind 1000s of genomic sites? Maybe they do, but the dozens of studies that report genomic binding maps of lncRNAs are deeply flawed, with probes binding suprious DNA sites rather than RNA-bound ones.
A preprint‼️that's bound to ruffle some 🪶 "Widespread DNA off-targeting confounds studies of RNA chromatin occupancy" led by our Micah Goldrich and Louis Delhaye from
Pieter Mestdagh in Ghent. TL;DR we show that many of lncRNA chromatin occupancy obtained are flawed www.biorxiv.org/content/10.1...

Excited to share our new preprint on EZH1-mediated H3K27me3 in the adult brain!

We show that postmitotic neurons accumulate high levels of H3K27me3 broadly across the genome. This is dependent on EZH1, but surprisingly not required for gene expression regulation:

We show that PRC1 condensates exclude SWI/SNF from chromatin, revealing a physical mechanism for how opposing regulators compete to control gene expression.

Huge thanks to all collaborators and mentors!

Accessory subunits of PRC2 mimic H3K27me3 to restrict the spread of Polycomb domains
Some proteins mimic the repressive mark H3K27me3, but the physiological relevance of this phenomenon was unclear. Agius et al. show that the PRC2 subunits JARID2 and PALI1 mimic H3K27me3 to antagonize PRC2-mediated H3K27me3 deposition, limit Polycomb domain spreading, and enable timely activation of developmental genes in vivo.
