摘要

异染色质是如何在早期胚胎中从头建立的尚不清楚。现在的一项研究表明，关键调控因子JARID2的顺序招募将PRC2.2招募到H2AK119ub，并确保适当的H3K27me2/3沉积。这可以防止增强子过早激活，而增强子激活对基因调控和品系规范至关重要。

Building the epigenetic fortress with PRC2.2

How heterochromatin is established de novo in early embryos is unknown. A study now shows that the sequential recruitment of the key regulator JARID2 recruits PRC2.2 to H2AK119ub and ensures proper H3K27me2/3 deposition. This prevents premature enhancer activation, which is crucial for gene regulation and lineage specification.
