Nucleosome-mediated synergism between transcription factors on the mouse mammary tumor virus promoter
(National Academy of Sciences, 1997)
In unstimulated mammalian cells and in Saccharomyces cerevisiae, the mouse mammary tumor virus (MMTV) promoter is silent and organized into positioned nucleosomes, one of which encompasses the binding sites for glucocorticoid ...

The presence of glutamate dehydrogenase is a selective advantage for the cyanobacterium Synechocystis sp. strain PCC 6803 under nonexponential growth conditions
(American Society for Microbiology, 1999)
he unicellular cyanobacterium Synechocystis sp. strain PCC 6803 has two putative pathways for ammonium assimilation: the glutamine synthetase- glutamate synthase cycle, which is the main one and is finely regulated by the ...

Nuclear functions of prefoldin
(The Royal Society, 2014)
Prefoldin is a cochaperone, present in all eukaryotes, that cooperates with the chaperonin CCT. It is known mainly for its functional relevance in the cytoplasmic folding of actin and tubulin monomers during cytoskeleton ...

A gene-specific requirement for FACT during transcription is related to the chromatin organization of the transcribed region
(2006)
The FACT complex stimulates transcription elongation on nucleosomal templates. In vivo experiments also involve FACT in the reassembly of nucleosomes traversed by RNA polymerase II. Since several features of chromatin ...

One step back before moving forward: regulation of transcription elongation by arrest and backtracking
(Wiley-Blackwell, 2012)
RNA polymerase II backtracking is a well-known phenomenon, but its involvement in gene regulation is yet to be addressed. Structural studies into the backtracked complex, new reactivation mechanisms and genome-wide approaches ...

Recruitment of a chromatin remodelling complex by the Hog1 MAP kinase to stress genes
(EMBO Press, 2009)
For efficient transcription, RNA PolII must overcome the presence of nucleosomes. The p38-related MAPK Hog1 is an important regulator of transcription upon osmostress in yeast and thereby it is involved in initiation and ...

Nucleo-cytoplasmic Shuttling of RNA-binding Factors: mRNA Buffering and Beyond
(Elsevier, 2022)
Gene expression is a highly regulated process that adapts RNAs and proteins content to the cellular context. Under steady-state conditions, mRNA homeostasis is robustly maintained by tight controls that act on both nuclear ...

The ribosome assembly gene network is controlled by the feedback regulation of transcription elongation
(Oxford University Press, 2017)
Ribosome assembly requires the concerted expression of hundreds of genes, which are transcribed by all three nuclear RNA polymerases. Transcription elongation involves dynamic interactions between RNA polymerases and ...
