The protein acetyltransferases p300 and cAMP response element-binding protein binding protein (CBP) are homologous, ubiquitously expressed proteins that interact with hundreds of proteins involved in transcriptional regulation and are involved globally as transcriptional coregulators. Although these two proteins acetylate and interact with overlapping sets(More)
Monascus species are traditionally used for food preservation. This study used the disc diffusion method to verify the antifungal activity of protein extracted from Monascus pilosus BCRC38072 against 15 fungal pathogens. An antifungal protein, designated as MAFP1, was successfully purified and confirmed through N-terminal sequencing. To further explore the(More)
Histone H3 lysine-9 methyltransferase G9a/EHMT2/KMT1C is a key corepressor of gene expression. However, activation of a limited number of genes by G9a (independent of its catalytic activity) has also been observed, although the precise molecular mechanisms are unknown. By using RNAi in combination with gene expression microarray analysis, we found that G9a(More)
Ligand activation and DNA-binding dictate the outcome of glucocorticoid receptor (GR)-mediated transcriptional regulation by inducing diverse receptor conformations that interact differentially with coregulators. GR recruits many coregulators via the well-characterized AF2 interaction surface in the GR ligand-binding domain, but Lin11, Isl-1, Mec-3 (LIM)(More)
ChIP seq is a widely used assay to measure genome-wide protein binding. The decrease in costs associated with sequencing has led to a rise in the number of studies that investigate protein binding across treatment conditions or cell lines. In addition to the identification of binding sites, new studies evaluate the variation in protein binding between(More)
Glucocorticoids are a class of steroid hormones that bind to and activate the glucocorticoid receptor (GR), which then positively or negatively regulates transcription of many genes that govern multiple important physiological pathways such as inflammation and metabolism of glucose, fat and bone. The remodeling of chromatin and regulated assembly or(More)
Like many transcription regulators, histone methyltransferases G9a and G9a-like protein (GLP) can act gene-specifically as coregulators, but mechanisms controlling this specificity are mostly unknown. We show that adjacent post-translational methylation and phosphorylation regulate binding of G9a and GLP to heterochromatin protein 1 gamma (HP1γ), formation(More)
Steroid receptors (SRs) bind specific DNA regulatory sequences, thereby activating and repressing gene expression. We previously showed that transcriptional coregulator Hic-5 facilitates glucocorticoid regulation of some genes but blocks glucocorticoid regulation of others. Here, in a genome-wide analysis, Hic-5 depletion dramatically increased the global(More)
