An acetyl-histone peptide library was used to determine the thermodynamic parameters that define acetylation-dependent bromodomain-histone interactions. Bromodomains interact with histones by binding acetylated lysines. The bromodomain used in this study, BrD3, is derived from the polybromo-1 protein, which is a subunit of the PBAF chromatin remodeling ...

Blue light-induced transcription in Neurospora crassa is regulated by the White Collar-1 (WC-1) photoreceptor. We report that residue K14 of histone H3 associated with the light-inducible albino-3 (al-3) promoter becomes transiently acetylated after photoinduction. This acetylation depends on WC-1. The relevance of this chromatin modification was directly ...
Increasing evidence suggests that AR (androgen receptor) acetylation is critical for prostate cancer cell growth. In the present study, we identified Pro-B3 (procyanidin B3) as a specific HAT (histone acetyltransferase) inhibitor. Pro-B3 selectively inhibited the activity of HATs, but not other epigenetic enzymes. Pro-B3 substantially inhibited the p300-mediated AR acetylation, both in vitro and ...
STAT1 signaling regulates the expression of important genes controlling cell growth, differentiation, apoptosis, and immune functions. Biochemical and genetic experiments have identified how this cascade is modulated. Phosphorylation of STAT1 tyrosine and serine moieties is induced rapidly by cytokines and growth factors.

Although most eukaryotic proteins are N-terminally acetylated, structural mechanisms by which N-terminal acetylation mediates protein interactions are largely unknown. Here, we found that N-terminal acetylation of the E2 enzyme, Ubc12, dictates distinctive E3-dependent ligation of the ubiquitin-like protein, Nedd8, to Cul1. Structural, biochemical, biophysical, and genetic analyses revealed how ...
Epigenetic modifications of histones regulate gene expression and lead to the establishment and maintenance of cellular phenotypes during development. Histone acetylation depends on a balance between the activities of histone acetyltransferases and histone deacetylases (HDACs) and influences transcriptional regulation. In this study, we analyse the roles ...
Histone acetyltransferases are associated with the elongating RNA polymerase II (Pol II) complex, supporting the idea that histone acetylation and transcription are intertwined mechanistically in gene coding sequences. Here, we studied the establishment and function of histone acetylation and transcription in noncoding sequences by using a model locus linking the beta-globin HS2 enhancer and the ...
