by mimicking planttranscriptional activators(Kay and Bonas, 2009). These transcriptional activators were found to contain a centralDNA bindingdomain composed oftandem repeatsthat recognized distinct nucleotides in a sequence. In particular, these tandem repeats of 34amino acidswere found...
Four ARFs function as activators and contain glutamine-rich activation domains. To achieve transcriptional activation on TGTCTC AuxREs in transient expression assays, ARFs require a conserved dimerization domain found in both ARF and Aux/IAA proteins, but they do not absolutely require their DNA-...
Activators and repressors of transcription: Using bioinformatics approaches to analyze and group human transcription factors.Transcription factors are macromolecules that are involved in transcriptional regulation by interacting with specific DNA regions, and they can cause activation or silencing of their ...
Transcriptional Regulation in Saccharomyces cerevisiae: Transcription Factor Regulation and Function, Mechanisms of Initiation, and Roles of Activators and... Transcriptional regulation in Saccharomyces cerevisiae: transcription factor regulation and function, mechanisms of initiation, and roles of activators and...
Following interactions with transcriptional activators at distal sites (not shown), the general transcriptional cofactors PC4 and Mediator might target multiple components of the general machinery and facilitate formation and/or function (initiation) of the PIC. Transcriptional cofactors can be broadly ...
Post: Activators of the anthocyanin biosynthesis belong to subgroup 6 of the R2R3-MYB family. In addition to the R2R3 domain, there are three short motifs conserved among anthocyanin regulators #MybMonday Rodrigues et al., 2021 identified functional variation in the C-terminal region of anthocyani...
CBF1-3 (C-repeat binding factors) are transcriptional activators governing plant responses to low temperatures. Overexpression of CBF1-3 genes enhances pla... M Sharabi-Schwager,A Samach,R Porat - 《Plant Signaling & Behavior》 被引量: 244发表: 2010年 The transcriptional activity of coactivator...
Instead of using DNA-binding activators, T4 bacteriophage activates the transcription of late genes by using a DNA-tracking protein, the sliding clamp, as the activator. As a proof of concept, fusion proteins linking the transcription activation domain of herpes simplex virus VP16 protein to a ...
(434/589) of the >2-fold DEGs, showing their importance in differentiating the two clusters. In particular, they regulate cell cycle pathways including cell cycle checkpoints, homology directed repair, G0/G1 and mitotic phases. Cell cycle activators are broadly overexpressed in CL2 and repressed...
Distinct GCN5/PCAF-containing complexes function as co-activators and are involved in transcription factor and global histone acetylation. Transcription in eukaryotes is a tightly regulated, multistep process. Gene-specific transcriptional activators, several different co-activators and genera... ZL Nagy,...
