Faithful inheritance: Parental histone recycling and epigenetic memory in fission yeast.
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.
