Here, we expound on the view that Xist RNA directly controls Polycomb repressive complex 2 (PRC2) recruitment, off-loading to chromatin, catalytic activity, and eviction from chromatin. RNA-PRC2 interactions also control RNA polymerase II transcription pausing. Dynamic RNA folding determines PRC2 activity. Disparate studies and interpretations abound but can be reconciled.
在这里，我们阐述了这样一种观点，即 Xist RNA 直接控制多梳抑制复合物 2（PRC2）的募集、向染色质的卸载、催化活性以及从染色质中的逐出。RNA-PRC2 相互作用还控制 RNA 聚合酶 II 转录暂停。动态 RNA 折叠决定了 PRC2 的活性。虽然存在着大量不同的研究和解释，但它们可以得到协调。
