( 2005 ) Specific function of a plastid sigma factor for ndhF gene transcription . Nucleic Acids Research 33 , 5991 – 5999 .Favory JJ, Kobayshi1 M, Tanaka1 K, Peltier G, Kreis M, Valay JG, Lerbs- Mache S: Specific function of a plastid sigma factor for ndhF gene transcription. ...
The present review aims to summarize these recent advances and to convince the reader that plastid gene expression is regulated on the transcriptional level by sigma factor action. 展开 关键词: Higher plants Plastid Transcription regulation Sigma factors ...
The σ factor σ 70 of E. coli RNA polymerase acts not only in initiation, but also at an early stage of elongation to induce a transcription pause, and simultaneously to allow the phage λ gene Q transcription antiterminator to act. We identify the signal in DNA that induces early pausing...
The extracytoplasmic function sigma factor σVreIof the human pathogenPseudomonas aeruginosapromotes transcription of potential virulence determinants, including secretion systems and secreted proteins. Its activity is modulated by the VreR anti-σ factor that inhibits the binding of σVreIto the RNA poly...
These screens and subsequent characterization revealed that overexpressing BATF3 supports specific features of memory T cells, counters T cell exhaustion and improves tumor control. We conducted pooled CRISPRko screens of all human transcription factor genes (TFome) with or without BATF3 OE to define...
[1–3]; As an upstream mediator of vascu- lar endothelial growth factor (VEGF), hypoxia-inducible factor-1 alpha (HIF-1α) is a significant transcription fac- tor for cellular response in hypoxia, and also promotes angiogenesis and boosts metabolism, thus provoking abnormal vascularization [4–...
Role of the RNA polymerase sigma subunit in transcription initiation In bacteria, σ subunits direct the catalytically competent RNA polymerase core enzyme to promoters. Recent advances in our understanding of bacterial RNA ... Sergei Borukhov a,Konstantin Severinov b - 《Research in Microbiology》 ...
Besides that, the transcription factor aryl hydrocarbon receptor (AhR) is a well-known pleiotropic sensor of environmental factors, which can be activated by UVB radiation59. AhR has been demonstrated to inhibit ILC2 function30, which raises another possibility that UVB may inhibit ILC2-mediated ...
To define the transcriptional program and transcription factors (TFs) that likely drive cell-state-specific regulatory programs, we employed chromVAR38to identify TF motif enrichments and examined the differences of single-cell-based enrichments among COVID-19 severity-relevant cell states in the CD14...
Guanylate binding protein 1 (GBP1) is the most concerned member of the GBP family, which has a series of effects such as anti-infection and anti-angiogenesis. Its role in malignant tumors including cervical cancer is still controversial. We aim to explor
