(Submitter supplied) Heterochromatic DNA domains play important roles in the regulation of gene expression and maintenance of genome stability by silencing repetitive DNA elements and transposons. In organisms ranging from fission yeast to mammals, heterochromatin assembly at DNA repeats involves the activity of small noncoding RNAs (sRNAs) associated with the RNA interference (RNAi) pathway. Typically, sRNAs, originating from long noncoding RNAs transcribed from DNA repeats, guide Argonaute-containing effector complexes to complementary nascent RNAs to initiate histone H3 lysine 9 di- and tri-methylation (H3K9me2 and H3K9me3, respectively) and heterochromatin formation. more...

(Submitter supplied) Histone H3 lysine 9 methylation (H3K9me) mediates heterochromatic gene silencing and is important for genome stability and the regulation of gene expression. The establishment and epigenetic maintenance of heterochromatin involve the recruitment of H3K9 methyltransferases to specific sites on DNA, followed by the recognition of pre-existing H3K9me by the methyltransferase and methylation of proximal histone H3. more...

(Submitter supplied) We tested the ability of trans siRNAs to establish a silent allele of endogenous ade6+ or an ade6+ transgene inserted within euchromatic loci. We found that a silent ade6-OFF epi-allele that grows red on low adenine medium could be established in several mutant backgrounds (mlo3∆, leo1∆) in the presence of ectopic siRNAs. Furthermore, we found that the silent ade6-OFF epi-allele could be meiotically inherited to wildtype progeny lacking the establishing mutation or ectopic siRNAs. more...

(Submitter supplied) Cellular quiescence (G0) is a ubiquitous stress response through which cells enter a state of reversible dormancy, acquiring distinct properties including reduced metabolism, resistance to stress and long life. G0 entry involves dramatic changes to the chromatin landscape and transcriptional program of cells, but the mechanisms coordinating these processes remain poorly understood. Using the fission yeast, here we track the G0-associated chromatin and transcriptional changes temporally. more...

(Submitter supplied) Regulation of heterochromatin is critical for genome stability. Different states of methylated H3K9 have been discovered with distinct roles in heterochromatin formation and silencing. However, the control of the transition from H3K9me2 to H3K9me3 is still unclear. Here we investigate the role of the conserved bromodomain AAA-ATPase, Abo1, involved in maintaining the global nucleosome organization in fission yeast. more...

(Submitter supplied) Methylation of histone H3 at lysine 9 (H3K9) is a hallmark of heterochromatin that plays crucial roles in chromatin-dependent gene silencing and maintenance of genome stability by repressing repetitive DNA elements and recruiting downstream factors essential for faithful chromosome segregation.

(Submitter supplied) H3K9 methylation (H3K9me) marks transcriptionally silent genomic regions called heterochromatin. A conserved class of HP1 proteins are critically required to establish and maintain heterochromatin. HP1 proteins bind to H3K9me, recruit factors that promote heterochromatin formation, and oligomerize to form phase-separated condensates. We do not understand how HP1 protein binding to heterochromatin establishes and maintains transcriptional silencing. more...
