Telomeric Heterochromatin in Plasmodium falciparum

Until very recently, little was known about the chromatin structure of the telomeres and subtelomeric regions in Plasmodium falciparum. In yeast and Drosophila melanogaster, chromatin structure has long been known to be an important aspect in the regulation and functioning of these regions. Telomeres and subtelomeric regions are enriched in epigenetic marks that are specific to heterochromatin,...

Differential maintenance of DNA sequences in telomeric and centromeric heterochromatin.

Repeated DNA in heterochromatin presents enormous difficulties for whole-genome sequencing; hence, sequence organization in a significant portion of the genomes of multicellular organisms is relatively unknown. Two sequenced BACs now allow us to compare telomeric retrotransposon arrays from Drosophila melanogaster telomeres with an array of telomeric retrotransposons that transposed into the ce...

Non-coding telomeric and subtelomeric transcripts are differentially regulated by telomeric and heterochromatin assembly factors in fission yeast

While telomere repeat-containing non-coding RNA has been identified in a variety of eukaryotes, its biological role is not yet clear. We have identified telomeric transcripts in fission yeast, a model system that combines precise genetic manipulability with telomeres remarkably similar to those of human. Like human and budding yeast, fission yeast harbours a population of telomeric RNA molecule...

Cellular aging is associated with increased ubiquitylation of histone H2B in yeast telomeric heterochromatin.

Epigenetic changes in chromatin state are associated with aging. Notably, two histone modifications have recently been implicated in lifespan regulation, namely acetylation at H4 lysine 16 in yeast and methylation at H3 lysine 4 (H3K4) in nematodes. However, less is known about other histone modifications. Here, we report that cellular aging is associated with increased ubiquitylation of histon...

A Distinct Type of Heterochromatin at the Telomeric Region of the Drosophila melanogaster Y Chromosome

Heterochromatin assembly and its associated phenotype, position effect variegation (PEV), provide an informative system to study chromatin structure and genome packaging. In the fruit fly Drosophila melanogaster, the Y chromosome is entirely heterochromatic in all cell types except the male germline; as such, Y chromosome dosage is a potent modifier of PEV. However, neither Y heterochromatin co...
