Abstract
Molecular mimicry is a commonly used mechanism by viruses to manipulate host cellular machinery and coordinate their life cycles. While histone mimicry is well studied, viruses also employ other mimicry strategies to affect chromatin dynamics. However, the relationship between viral molecular mimicry and host chromatin regulation is not well understood. This review summarizes recent advances in histone mimicry and explores how viral molecular mimicry influences chromatin dynamics. We also discuss how viral proteins interact with both intact and partially unfolded nucleosomes and compare the distinct mechanisms governing chromatin tethering. Finally, we address the role of viral molecular mimicry in regulating chromatin dynamics. This review provides new insights into viral molecular mimicry and its impact on host chromatin dynamics, paving the way for the development of novel antiviral strategies.
