Molecular Genetics of T Cell Development [PDF]
, 2005 T cell development is guided by a complex set of transcription factors that act recursively, in different combinations, at each of the developmental choice points from T-lineage specification to peripheral T cell specialization. This review describes the

Microbiology, 2008 Gene expression is a fundamental process that is highly conserved from humans to bacteria. The first step in gene expression, transcription, is performed by structurally conserved DNA-dependent RNA polymerases (RNAPs), which results in the synthesis of an RNA molecule from a DNA template.

Transcription factors organize into functional groups on the linear genome and in 3D chromatin
Heliyon, 2023 Transcription factors (TFs) and their binding sites have evolved to interact cooperatively or competitively with each other. Here we examine in detail, across multiple cell lines, such cooperation or competition among TFs both in sequential and spatial ...

Fungal CSL transcription factors
BMC Genomics, 2007 Background The CSL (CBF1/RBP-Jκ/Suppressor of Hairless/LAG-1) transcription factor family members are well-known components of the transmembrane receptor Notch signaling pathway, which plays a critical role in metazoan development.

Transposon-derived transcription factors across metazoans
Frontiers in Cell and Developmental Biology, 2023 Transposable elements (TE) could serve as sources of new transcription factors (TFs) in plants and some other model species, but such evidence is lacking for most animal lineages. Here, we discovered multiple independent co-options of TEs to generate 788

How the DNA sequence affects the Hill curve of transcriptional response [PDF]
Phys. Biol. 9 (2012) 056006, 2011 The Hill coefficient is often used as a direct measure of the cooperativity of binding processes. It is an essential tool for probing properties of reactions in many biochemical systems. Here we analyze existing experimental data and demonstrate that the Hill coefficient characterizing the binding of transcription factors to their cognate sites can in ...

TFE and Spt4/5 open and close the RNA polymerase clamp during the transcription cycle [PDF]
, 2016 Transcription is an intrinsically dynamic process and requires the coordinated interplay of RNA polymerases (RNAPs) with nucleic acids and transcription factors.

Smad transcription factors [PDF]
Genes & Development, 2005 Smad transcription factors lie at the core of one of the most versatile cytokine signaling pathways in metazoan biology—the transforming growth factor-β (TGFβ) pathway. Recent progress has shed light into the processes of Smad activation and deactivation, nucleocytoplasmic dynamics, and assembly of transcriptional complexes.

Regulation of Transcription Elongation and Termination
Biomolecules, 2015 This article will review our current understanding of transcription elongation and termination in E. coli. We discuss why transcription elongation complexes pause at certain template sites and how auxiliary host and phage transcription factors affect ...

A role for ATP-dependent chromatin remodeling in the hierarchical cooperativity between noninteracting transcription factors [PDF]
J. Theor. Biol. 287, 74-81 (2011), 2015 Chromatin remodeling machineries are abundant and diverse in eukaryotic cells. They have been involved in a variety of situations such as histone exchange and DNA repair, but their importance in gene expression remains unclear. Although the influence of nucleosome position on the regulation of gene expression is generally envisioned under the quasi ...
