Abstract

Accurate transmission of chromatin states during DNA replication is central to epigenetic inheritance. Recent advances have illuminated mechanisms by which parental histones, which carry key post-translational modifications, are recycled and redistributed to daughter strands. This review synthesizes emerging insights into the molecular machinery that mediates histone recycling during replication. It highlights the interplay between histone chaperones and replication factors and examines how perturbations in these pathways influence heterochromatin inheritance. The fission yeast serves as a powerful model for recent investigations, revealing new principles that are conserved across eukaryotes.

摘要

染色质状态在DNA复制过程中的准确传递是表观遗传的核心。最近的进展揭示了携带关键翻译后修饰的亲本组蛋白被循环利用并重新分布到子链的机制。这篇综述综合了对复制过程中介导组蛋白循环利用的分子机制的新见解。它强调了组蛋白伴侣与复制因子之间的相互作用,并探讨了这些途径中的扰动如何影响异染色质遗传。裂殖酵母是近期研究的一个有力模型,揭示了在整个真核生物中保守的新原则。
