Weblated histone H3 and MeCP2 (1, 7), the latter being a MBD protein known to associate with HDAC-containing co-repressor complexes (10). This finding suggests a methylation-dependent mechanism for retroviral silencing in MEL cells that involves specific recruitment of HDACs to methylated DNA through MBD proteins. Web11 de set. de 2024 · pluripotent cells is the repression of retroviral sequences’ transcription through heterochromatinization, which blocks the binding of transcriptional activators [3–11]. In many cases, a similar mechanism limits the expression of genes delivered by retroviral vectors [12] and is responsible for both exogenous and ERV silencing [3,6,11].

Together, these data suggest a direct and variant-specific role for H3.3 in establishing H3K9me3 chromatin at a subset of ERVs that cannot be compensated by the canonical H3.1/2 isoforms. 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].
