多梳族蛋白 (PcG) 是后生动物适当发育调节和细胞命运决定所必需的。最近,四项研究报道了 JARID2(一种含有 JmjC 结构域的蛋白)的鉴定,它是 Polycomb 抑制复合物 2 (PRC2) 的一个组成部分,该复合物参与发育过程中组蛋白 H3 Lys 27 甲基化和转录抑制。在这里,我们讨论这些研究对于加深对发育中 PcG 功能的理解的影响。
Polycomb group proteins (PcG) are required for proper developmental regulation and cell fate commitment in metazoans. Recently, four studies reported the identification of JARID2, a JmjC domain-containing protein, as a component of the Polycomb-repressive complex 2 (PRC2), which is involved in implementing histone H3 Lys 27 methylation and transcriptional repression during development. Here, we discuss the implications of these studies for an improved understanding of PcG function in development.
