WebH3.3 is specifically enriched on endogenous retroviruses (ERV), together with Trim28 and H3K9me3. Several pressing questions about the role of H3.3 in retroviral silencing are unanswered: when is H3.3 loaded into the viral genome? is H3.3 needed for Trim28 recruitment to the retroviral genome? Or is it the other way around?

In this work, we address the role of such H3K9me2/3 "readers" in the silencing of ERVs in mESCs.
Web1 de out. de 2024 · ASF1A and ASF1B appear to play redundant roles in this process, as individual knockdown down of either one of them did not cause any effect on retroviral silencing [14 ••]. Interestingly, another recent study suggests that H3.3 may also repress the activities of a subset of ERVs, mostly the intracisternal A particle (IAP) [18].
