Illumination is necessary and sufficient to induce histone acetylation independent of transcriptional activity at the C4-specific phosphoenolpyruvate carboxylase promoter in maize.
Expression of the C4-specific phosphoenolpyruvate carboxylase (C4-PEPC) gene in maize (Zea mays) is regulated in a tissue-specific manner, but affected by light and nutrient availability. We manipulated these stimuli in a combinatorial manner and analyzed concomitant changes in histone acetylation of the nucleosomes associated with the C4-PEPC gene in relation to transcriptional activity and st...
متن کاملHDAC Activity Is Required for Efficient Core Promoter Function at the Mouse Mammary Tumor Virus Promoter
Histone deacetylases (HDACs) have been shown to be required for basal or inducible transcription at a variety of genes by poorly understood mechanisms. We demonstrated previously that HDAC inhibition rapidly repressed transcription from the mouse mammary tumor virus (MMTV) promoter by a mechanism that does not require the binding of upstream transcription factors. In the current study, we find ...
متن کاملThyroid transcription factor 1 phosphorylation is not required for protein kinase A-dependent transcription of the thyroglobulin promoter.
Thyroid transcription factor 1 (TTF1) is a nuclear homeodomain protein that binds to and activates the promoters of several thyroid-specific genes, including that of the thyroglobulin gene (pTg). These genes are also positively regulated by thyroid-stimulating hormone/cyclic AMP (cAMP)/protein kinase A (PKA) signaling. We asked whether PKA directly activates TTF1. We show that cAMP/PKA activate...
متن کاملLinking Core Promoter Classes to Circadian Transcription
Circadian rhythms in transcription are generated by rhythmic abundances and DNA binding activities of transcription factors. Propagation of rhythms to transcriptional initiation involves the core promoter, its chromatin state, and the basal transcription machinery. Here, I characterize core promoters and chromatin states of genes transcribed in a circadian manner in mouse liver and in Drosophil...
متن کاملCore promoter-selective RNA polymerase II transcription.
The initiation of mRNA synthesis in eukaryotic cells is a complex and highly regulated process that requires the assembly of general transcription factors and RNAP II (RNA polymerase II; also abbreviated as Pol II) into a pre-initiation complex at the core promoter. The core promoter is defined as the minimal DNA region that is sufficient to direct low levels of activator-independent (basal) tr...
