(2) As a result, transcription factors are activated/de-activated and/or epigenetic signals are added to (or removed from) DNA in response - For example: transcription factors bind to DNA upstream of a gene and attract the attention of the transcription machinery. - For example: a methyl gr...

To reach their binding sites, TFs diffuse in 3D and perform local ...
This chapter describes the properties of transcription factors which allow them to bind to DNA and influence the rate of transcription either positively or negatively. When combined with the synthesis or activation of many of these factors only in specific cell types, these properties allow ...
Transcription factors (TFs) bind to different parts of the genome in different types of cells, but it is usually assumed that the inherent DNA-binding pref... Aseel Awdeh,Marcel Turcotte,Theodore J. Perkins - BMC Genomics 被引量: 0发表: 2024年 Gene-specific regulation by general translation...
However, the DNA-binding specificities of ~1400 human transcription factors are largely unknown. The in vivo DNA-binding events of transcription factors involve great subtlety, because most transcription factors recognise degenerate sequence ... X Chen 被引量: 0发表: 2012年 Novel Sequence-Based Metho...
12、ic RNA-pol requires co-factors to bind to the DNA template together in the transcription process. 2.1 Transcription of ProkaryotesInitiation phase: RNA-pol recognizes the promoter and starts the transcription. Elongation phase: the RNA strand is continuously growing. Termination phase: the RNA-...
Some transcription factors have been proposed to functionally interact with RNA to facilitate proper regulation of gene expression. Here the authors demonstrate that human Sox2 interact directly and with high affinity to RNAs through its HMG DNA-binding domain. Zachariah E. Holmes , Desmond J. Hamilt...
Calcium can also directly regulate transcription factors. Calcium binding to the transcriptional repressor DREAM (downstream-response-element-antagonist modulator) inhibits the ability of DREAM to bind DNA, relieving the repression of target genes such as prodynorphin.Dream-knockout mice show altered pain...

Cooperation and cooperativity of transcription factors As discussed above, highly expressed TFs can directly bind to DNA, although ultimately this depends on a trade-off among effective concentrations, interaction constants, and number of potential binding sites. To win on all accounts, some TFs contai...
