WebFeb 7, 2024 · Although not common, editing at canonical cis-acting elements can result in dramatic changes in splicing and gene expression, since it can completely abolish … These findings mostly concern cis-regulatory elements, which are sequences controlling gene expression at all developmental stages. They comprise of promoters, enhancers, insulators and silencers, which are used to construct synthetic expression cassettes. See more Examples. An example of a cis-acting regulatory sequence is the operator in the lac operon. This DNA sequence is bound by the lac repressor, … See more A noncoding DNA sequence in or near a gene required for proper spatiotemporal expression of that gene, often containing binding sites for transcription factors. Often used … See more In the simplest terms, gene promoters are DNA sequences located upstream of gene coding regions and contain multiple cis-acting elements, which are specific binding sites for proteins … See more Cis-regulatory modules (CRMs) are DNA sequence elements that have transcriptional regulatory activity. Some CRMs are promoter … See more

WebOne of the mechanisms through which protein levels in the cell are controlled is through transcriptional regulation. Certain regions, called cis-regulatory elements, on the DNA are footprints for the trans-acting proteins involved in transcription, either for the positioning of the basic transcriptional machinery or for the regulation - in simple terms turn on or turn … Webcis.
