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

Enhancer remodeling by OTX2 directs specification and patterning of mammalian definitive endoderm
Correct patterning of emerging tissues in the developing embryo is essential for the formation of functional organ systems. Using genetic tools for controlled protein depletion, Ee et al. identify the...

Distinct specificity and functions of PRC2 subcomplexes in human stem cells and cardiac differentiation
Much et al. reveal that the PRC2 subcomplexes PRC2.1 and PRC2.2 play distinct roles in the epigenetic repression of developmental genes in human stem cells. Interactions between the PRC2 core and its accessory proteins, DNA, and H3K36me3 dictate PRC2 activity and, ultimately, modulate cardiac differentiation and function.

Excited to share our work on the specificity of PRC2 subcomplexes in stem cell and differentiation. We show that PRC2.1 and PRC2.2 exhibit distinct H3K27 methylation specificity in human pluripotent stem cells and opposing role in differentiation.
