Insights into the synchronization between DNA replication and parental histone recycling.

Accurate parental histone recycling is of pivotal importance in epigenetic inheritance. Its proper functioning hinges on the precise co-ordination among a diverse array of proteins. During DNA replication, any aberration in the distribution of parental histones can potentially result in the loss of epigenetic memory. To date, although several key proteins involved in parental histone recycling have been identified, the detailed molecular mechanisms underlying their functions remain elusive. This mini-review focuses on summarizing the synchrony between DNA replication and parental histone recycling, along with the key participants in parental histone recycling. In the end, we provide an overview of the inherent connection between parental histone recycling and epigenetic inheritance, shedding light on the fundamental role of histone recycling in maintaining epigenetic information across cell divisions.
