This trimeric Smad complex binds to regulatory sequences in the E cadherin promoter, leading its repression and subsequent loss of adherens junctions [ 12].
ChIP-seq data from multiple studies in different cell line backgrounds reveal that BRG1, as expected, binds to regulatory sequences at target genes but also binds elsewhere throughout the genome, with a significant proportion of the total binding sites being intergenic.
The processed miRNAs most frequently bind to regulatory sequences in the 3'- untranslated region (UTR) of target mRNAs through imperfect base-pairing, resulting in translational inhibition or degradation of protein-coding transcripts [2].
IRP's bind to regulatory sequences in the Tfrc mRNA 3' untranslated region and stabilize the messenger RNA promoting production of transferrin receptor protein [42], [43], [44] thereby increasing iron delivery.
This raises the possibility that critical DNA demethylation may facilitate transcription factor(s) downstream of CSF2 to bind to regulatory sequences of CD24 and MMP-2, with a consequential increase in Wnt/β-catenin signaling, which has been previously reported in pterygium [41].
Key to this control is the recruitment of transcription factors (TFs) that bind to regulatory sequences, such as promoters, enhancers, repressors and insulators.
Rather, our results suggest the presence of a regulatory protein in Mishca protoplasts that responds to UV-B, which may be able to bind to regulatory sequences in the promoter of P1.
The homeodomain, with its helix-turn-helix structure, binds to regulatory DNA sequences of target genes, while the LIM domains are mainly involved in protein-protein interactions that regulate the activity of the LIM-HD [ 22].
Finally, we found Desmoplakin to be a direct transcriptional target of Bcl11b in dentate granule cells, and demonstrate that Bcl11b binds directly to regulatory sequences in close proximity to the transcription start site of Dsp, which includes putative Bcl11b binding sites (Avram et al, 2002; Cismasiu et al, 2006).
Activated JAK2 auto-phosphorylates its receptors, and additionally phosphorylates STAT3, which results in the dimerization and translocation of STAT3 into the nucleus, where it binds to specific regulatory sequences to activate or repress transcription of target genes [ 37].
The exd protein binds in a highly co-operative manner to regulatory sequences mediating PS7-specific dpp expression, consistent with a genetic requirement for exd function in normal visceral mesoderm expression of dpp.
