Artificially recruited TATA-binding protein fails to remodel chromatin and does not activate three promoters that require chromatin remodeling.
Transcriptional activators are believed to work in part by recruiting general transcription factors, such as TATA-binding protein (TBP) and the RNA polymerase II holoenzyme. Activation domains also contribute to remodeling of chromatin in vivo. To determine whether these two activities represent distinct functions of activation domains, we have examined transcriptional activation and chromatin ...
متن کاملThe Chromatin-Remodeling Factor PICKLE Integrates Brassinosteroid and Gibberellin Signaling during Skotomorphogenic Growth in Arabidopsis.
Plant cell elongation is controlled by endogenous hormones, including brassinosteroid (BR) and gibberellin (GA), and by environmental factors, such as light/darkness. The molecular mechanisms underlying the convergence of these signals that govern cell growth remain largely unknown. We previously showed that the chromatin-remodeling factor PICKLE/ENHANCED PHOTOMORPHOGENIC1 (PKL/EPP1) represses ...

متن کاملES cell pluripotency and germ-layer formation require the SWI/SNF chromatin remodeling component BAF250a.
ATP-dependent chromatin remodeling complexes are a notable group of epigenetic modifiers that use the energy of ATP hydrolysis to change the structure of chromatin, thereby altering its accessibility to nuclear factors. BAF250a (ARID1a) is a unique and defining subunit of the BAF chromatin remodeling complex with the potential to facilitate chromosome alterations critical during development. Ou...
متن کاملChromatin Remodeling Complexes: The Regulators of Genome Function
Genome in eukaryotes is large enough to be accommodated in tiny nucleus. It is required to achieve high degree of compaction for getting into the nucleus. Compaction is achieved by folding the DNA in the form of chromatin. But chromatin acts as general repressor for the entire genomic functions. Therefore, it requires being selectively unpacked for gene expression. However this packing and unpa...
