Holding on through DNA replication: histone modification or modifier?
Abstract
Histone methylation is widely believed to contribute to epigenetic inheritance by persevering through DNA replication and subsequently templating methylation of daughter chromosome regions. However, a report in this issue (Petruk et al.) suggests that chromatin association of the methytransferase complexes themselves persists through replication and re-establishes histone methylation.
