Dynamics of gene expression and the regulatory inference problem [PDF]
, 2007 From the response to external stimuli to cell division and death, the dynamics of living cells is based on the expression of specific genes at specific times. The decision when to express a gene is implemented by the binding and unbinding of transcription factor molecules to regulatory DNA.

Genome-wide discovery of modulators of transcriptional interactions in human B lymphocytes [PDF]
RECOMB'06 Proceedings, LNCS 3909, Springer, 2006, 2005 Transcriptional interactions in a cell are modulated by a variety of mechanisms that prevent their representation as pure pairwise interactions between a transcription factor and its target(s). These include, among others, transcription factor activation by phosphorylation and acetylation, formation of active complexes with one or more co-factors, and ...

Coding limits on the number of transcription factors [PDF]
BMC Genomics 2006, 7:239, 2010 Transcription factor proteins bind specific DNA sequences to control the expression of genes. They contain DNA binding domains which belong to several super-families, each with a specific mechanism of DNA binding. The total number of transcription factors encoded in a genome increases with the number of genes in the genome. Here, we examined the number

Non-equilibrium dynamics of gene expression and the Jarzynski equality [PDF]
, 2007 In order to express specific genes at the right time, the transcription of genes is regulated by the presence and absence of transcription factor molecules. With transcription factor concentrations undergoing constant changes, gene transcription takes place out of equilibrium.

Dynamics of transcription factor binding site evolution [PDF]
, 2015 Evolution of gene regulation is crucial for our understanding of the phenotypic differences between species, populations and individuals. Sequence-specific binding of transcription factors to the regulatory regions on the DNA is a key regulatory ...

Transcription Factor Dynamics [PDF]
Cold Spring Harbor Perspectives in Biology, 2021 To predict transcription, one needs a mechanistic understanding of how the numerous required transcription factors (TFs) explore the nuclear space to find their target genes, assemble, cooperate, and compete with one another. Advances in fluorescence microscopy have made it possible to visualize real-time TF dynamics in living cells, leading to two ...

mBio, 2020 Bacterial gene regulation is governed by often hundreds of transcription factors (TFs) that bind directly to targets on the chromosome. Global studies of TFs usually make assumptions that regulatory targets within model strains will be conserved between ...

A compendium of Caenorhabditis elegans regulatory transcription factors: a resource for mapping transcription regulatory networks [PDF]
, 2005 Background Transcription regulatory networks are composed of interactions between transcription factors and their target genes. Whereas unicellular networks have been studied extensively, metazoan transcription regulatory networks remain largely ...

PLoS Computational Biology, 2013 Despite explosive growth in genomic datasets, the methods for studying epigenomic mechanisms of gene regulation remain primitive. Here we present a model-based approach to systematically analyze the epigenomic functions in modulating transcription factor-

The databases of transcription factors [PDF]
Hereditas (Beijing), 2011 The control of gene transcription is a critical level of gene expression regulation. The interactions between transcription factors (TF) and their DNA binding sites (TFBS) play a key role at this level. In order to decipher the molecular mechanism of the interactions of TFs with TFBSs and construct transcription regulatory network, it is necessary to ...
