Epigenetic engineering: histone H3K9 acetylation is compatible with kinetochore structure and function.
Human kinetochores are transcriptionally active, producing very low levels of transcripts of the underlying alpha-satellite DNA. However, it is not known whether kinetochores can tolerate acetylated chromatin and the levels of transcription that are characteristic of housekeeping genes, or whether kinetochore-associated 'centrochromatin', despite being transcribed at a low level, is essentially...
متن کاملHistone acetylation and an epigenetic code.
The enzyme-catalyzed acetylation of the N-terminal tail domains of core histones provides a rich potential source of epigenetic information. This may be used both to mediate transient changes in transcription, through modification of promoter-proximal nucleosomes, and for the longer-term maintenance and modulation of patterns of gene expression. The latter may be achieved by setting specific pa...
متن کاملHistone methylation versus histone acetylation: new insights into epigenetic regulation.
Post-translational addition of methyl groups to the amino-terminal tails of histone proteins was discovered more than three decades ago. Only now, however, is the biological significance of lysine and arginine methylation of histone tails being elucidated. Recent findings indicate that methylation of certain core histones is catalyzed by a family of conserved proteins known as the histone methy...
متن کاملEpigenetic engineering reveals a balance between histone modifications and transcription in kinetochore maintenance
Centromeres consist of specialized centrochromatin containing CENP-A nucleosomes intermingled with H3 nucleosomes carrying transcription-associated modifications. We have designed a novel synthetic biology 'in situ epistasis' analysis in which H3 dimethylated on lysine 4 (H3K4me2) demethylase LSD2 plus synthetic modules with competing activities are simultaneously targeted to a synthetic alphoi...
متن کاملH3K9 histone acetylation predicts pluripotency and reprogramming capacity of ES cells.
The pluripotent genome is characterized by unique epigenetic features and a decondensed chromatin conformation. However, the relationship between epigenetic regulation and pluripotency is not altogether clear. Here, using an enhanced MEF/ESC fusion protocol, we compared the reprogramming potency and histone modifications of different embryonic stem cell (ESC) lines (R1, J1, E14, C57BL/6) and fo...
