WebThere are four cis -regulatory elements in the Foxp3 locus, important for the regulation of gene expression: the promoter and three enhancers. The promoter contains response elements for transcription factors downstream of TCR/costimulation, such as NFAT, AP-1, and Nr4a family members and for STAT5, which is activated by IL-2 signaling.
Webcis-and trans- Regulatory ElementsThe lac operon includes DNA sequences that do not encode proteins, but are instead binding sites for proteins that regulate transcription of the operon. In the lac operon, these sequences are called P (promoter), O (operator), and CBS (CAP-binding site). Collectively, sequence elements such as these are called cis … WebOct 10, 2015 · Gene promoters and enhancers are examples of cis -regulatory regions (Table 1) that often show nucleosome depletion. At the promoters of highly expressed genes, nucleosomes are located just upstream and downstream of the transcription start site (TSS), thereby creating a nucleosome depleted region.
