Cis-acting sequences
WebRegulation of alternative RNA splicing by exon sequences is largely attributable to the presence of two major cis-acting elements in the regulated exons, the exonic splicing … 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 …

WebA cis -acting element for the sulfur response is reported for the Arabidopsis SULTR1;1 sulfate transporter gene ( Maruyama-Nakashita et al., 2005 ). The sulfur-responsive region of SULTR1;1 existed in the 5′-upstream region between − 2777 and − 2762 of its coding sequence. This region was named SURE after sulfur-responsive element.
WebCis-acting anti-repression sequences which can relieve the cis-acting repression in the presence of the art gene product are also disclosed. These sequences correspond to a … WebSplicing regulatory element (SRE) are cis -acting sequences in pre-mRNA, which either enhance or silence (suppress) the splicing of introns, or in general regulates the constitutive or alternative splicing of this pre-mRNA. SREs recruit trans -acting splicing factors to activate or suppress the splice site recognition or spliceosome assembly.
