A transcription factor affinity-based code for mammalian ... A transcription factor affinity-based code for mammalian transcription initiation ... We reasoned that if the Pol II transcription machinery were guided by direct or indirect binding to a subcollection of such
By decreasing the affinity of the polymerase for DNA, δ subnunit allows the enzumes to rapidly scan the DNA for a promoter. The δ subunit also assists the enzyme in identifying the promoter. ... making DNA more accessible to the transcription machinery.
Using ENCODE's recent release, a total of 425 ChIP-seq experiments studying 122 TFs in 95 different cell cultures were considered initially for this study totaling 1,702,787 unique ChIP-seq peaks. We removed experiments investigating basic transcription machinery Polymerase I, II and III and non-canonical TF CTCF.

The recruitment of the transcription machinery has long been thought to be an important rate-limiting step in gene expression . Concepts in transcription initiation by all three RNA polymerases (I, II, and III) have been guided by this basic theme .
Sep 25, 2001 The forkhead box (Fox) family of transcription factors share homology in the winged helix/forkhead DNA-binding domain and play important roles in regulating cellular proliferation, differentiation, longevity, and cellular transformation. Forkhead box M1B (FoxM1B) is a ubiquitously expressed member of the Fox transcription factor family whose expression is restricted to
The p300-CBP coactivator family is composed of two closely related transcriptional co-activating proteins (or coactivators): ... recruiting the basal transcriptional machinery including RNA polymerase II to the promoter. ... p300 regulates transcription by directly binding to transcription factors (see external reference for explanatory image).
The prevalence of autism spectrum disorder (ASD) has been increasing steadily over the last 20 years; however, the molecular basis for the majority of ASD cases remains unknown. Recent advances in next-generation sequencing and detection of DNA modifications have made methylation-dependent regulation of transcription an attractive hypothesis for being a causative factor in ASD etiology.
Understanding plant gene promoter architecture has long been a challenge due to the lack of relevant large-scale data sets and analysis methods. Here, we present a publicly available, large-scale transcription start site ([TSS]) data set in plants using a high-resolution method for analysis of 5′ ends of mRNA transcripts. Our data set is produced using the paired-end analysis of ...
It is well known that gene expression in eukaryotes is initiated by binding of transcription factors (TFs) and cofactors to the core promoter of the gene which signals RNA polymerase II transcription machinery. RNA polymerase II transcription machinery binds to the core promoter and specifies the transcription initiation site and direction.
