Journal ArticleDOI
Histone H3 and H4 N-termini interact with SIR3 and SIR4 proteins: A molecular model for the formation of heterochromatin in yeast
TL;DR: It is shown that the SIR3 and SIR4 proteins interact with specific silencing domains of the H3 and H4 N-termini in vitro, which proposes a model for heterochromatin-mediated transcriptional silencing in yeast, which may serve as a paradigm for other eukaryotic organisms as well.
Journal ArticleDOI
SIR2 and SIR4 interactions differ in core and extended telomeric heterochromatin in yeast.
TL;DR: It is proposed that the structure of core telomeric heterochromatin differs from that extended by SIR3, and that SIR2, Sir3, SIR4, and RAP1 map to the same sites along telomere position effect in wild-type cells.
Journal ArticleDOI
The p300/CBP acetyltransferases function as transcriptional coactivators of β‐catenin in vertebrates
TL;DR: It is demonstrated that the closely related acetyltransferases p300 and CBP potentiate β‐catenin‐mediated activation of the siamois promoter, a known Wnt target, and synergize to stimulate a synthetic reporter gene construct.
Journal ArticleDOI
Spreading of transcriptional repressor SIR3 from telomeric heterochromatin
TL;DR: SIR3 is a structural component of yeast heterochromatin, repressing adjacent genes as it spreads along the chromosome, suggesting the presence of large chromatin-associated protein complexes.
Journal ArticleDOI
Mediator Is a Transducer of Wnt/β-Catenin Signaling
TL;DR: It is shown that β-catenin physically and functionally targets the MED12 subunit in Mediator to activate transcription and is identified as a new component and a potential therapeutic target in the Wnt/β- catenin pathway.
