Cis-regulatory elements example
WebDec 5, 2024 · Cis-regulatory elements, such as promoters, enhancers, and silencers, are regions of non-coding DNA, which regulate the transcription of nearby genes. In contrast, trans-regulatory factors regulate (or modify) the expression of distant genes by combining with their target sequences [ 1, 2 ].

WebMar 31, 2024 · The promoter sequences of certain CsJAZ genes lacked some types of cis-acting regulatory elements, but the expression patterns revealed that all CsJAZ genes could respond to all five treatments. For example, we could not find high temperature response-related cis -acting regulatory elements in each CsJAZ gene of tea plants. An example of a cis-acting regulatory sequence is the operator in the lac operon. This DNA sequence is bound by the lac repressor, which, in turn, prevents transcription of the adjacent genes on the same DNA molecule. The lac operator is, thus, considered to "act in cis" on the regulation of the nearby … See more Cis-regulatory elements (CREs) or Cis-regulatory modules (CRMs) are regions of non-coding DNA which regulate the transcription of neighboring genes.
