Cis-regulatory elements (CREs) or cis-regulatory modules (CRMs) are regions of non-coding DNA which regulate the transcription of neighboring genes.CREs are vital components of genetic regulatory networks, which in turn control morphogenesis, the development of anatomy, and other aspects of embryonic development, studied in evolutionary developmental biology.
The strict regulation of translation in both space and time is in part governed by cis-regulatory elements located in 5′ mRNA transcript leaders (TLs) and 3′ untranslated regions (UTRs). Due to their role in translation initiation, mRNA 5′ transcript leaders (TLs) strongly influence protein expression.
CNSs in plants [2] and animals [1] are highly associated with transcription factor binding sites and other cis-acting regulatory elements. Conserved non-coding sequences can be important sites of evolutionary divergence [3] as mutations in these regions may alter the regulation of conserved genes, producing species-specific patterns of gene ...
Cis-regulatory DNA sequences that are located in DNA regions distant from the promoters of genes can have very large effects on gene expression, with some genes undergoing up to 100-fold increased expression due to such a cis-regulatory sequence. [36] These cis-regulatory sequences include enhancers, silencers, insulators and tethering elements ...
This is a list of cis-regulatory RNAs. These are RNA motifs which regulate nucleic acid regions on the same molecule, as opposed to trans -acting motifs which regulate a distal molecule. Some of these RNAs are broadly distributed while others are single RNA families.
Cis-regulatory elements are frequent targets of evolution resulting in varied morphology. [19] When looking at long-term evolution, mutations in cis-regulatory regions appear to be even more common. [20] In other words, more interspecific morphological differences are caused by mutations in cis-regulatory regions than intraspecific differences ...
The product of each gene can regulate the expression level of itself and/or the other genes through cis-regulatory elements. The interactions among genes constitute a gene network that is represented by a N {\displaystyle N} × N {\displaystyle N} regulatory matrix ( R ) {\displaystyle (R)} in the model.
Cis-regulatory DNA sequences that are located in DNA regions distant from the promoters of genes can have very large effects on gene expression, with some genes undergoing up to 100-fold increased expression due to such a cis-regulatory sequence.
