Distribution and Maintenance of Histone H3 Lysine 36 Trimethylation in Transcribed Locus
Post-translational modifications of core histones play an important role in the epigenetic regulation of chromatin dynamics and gene expression. In Saccharomyces cerevisiae methylation marks at K4, K36, and K79 of histone H3 are associated with gene transcription. Although Set2-mediated H3K36 methylation is enriched throughout the coding region of active genes and prevents aberrant transcriptio...
متن کاملHistone H3 lysine 4 trimethylation marks meiotic recombination initiation sites.
The function of histone modifications in initiating and regulating the chromosomal events of the meiotic prophase remains poorly understood. In Saccharomyces cerevisiae, we examined the genome-wide localization of histone H3 lysine 4 trimethylation (H3K4me3) along meiosis and its relationship to gene expression and position of the programmed double-strand breaks (DSBs) that initiate interhomolo...
متن کاملReversal of Histone Lysine Trimethylation by the JMJD2 Family of Histone Demethylases
Histone methylation regulates chromatin structure, transcription, and epigenetic state of the cell. Histone methylation is dynamically regulated by histone methylases and demethylases such as LSD1 and JHDM1, which mediate demethylation of di- and monomethylated histones. It has been unclear whether demethylases exist that reverse lysine trimethylation. We show the JmjC domain-containing protein...
متن کاملThe regulatory repertoire of PLZF and SALL4 in undifferentiated spermatogonia.
Spermatogonial stem cells (SSCs) maintain spermatogenesis throughout adulthood through balanced self-renewal and differentiation, yet the regulatory logic of these fate decisions is poorly understood. The transcription factors Sal-like 4 (SALL4) and promyelocytic leukemia zinc finger (PLZF; also known as ZBTB16) are known to be required for normal SSC function, but their targets are largely unk...
متن کاملAcute stress and hippocampal histone H3 lysine 9 trimethylation, a retrotransposon silencing response.
The hippocampus is a highly plastic brain region particularly susceptible to the effects of environmental stress; it also shows dynamic changes in epigenetic marks in response to stress and learning. We have previously shown that, in the rat, acute (30 min) restraint stress induces a substantial, regionally specific, increase in hippocampal levels of the repressive histone H3 lysine 9 trimethyl...
