WebJul 11, 2024 · Cis-regulatory effects are measured using the differential expression of allele-specific reads within the hybrid samples, whereas trans-regulatory effects are … Cis-regulatory elements are often binding sites for one or more trans-acting factors. To summarize, cis-regulatory elements are present on the same molecule of DNA as the gene they regulate whereas trans-regulatory elements can regulate genes distant from the gene from which they were transcribed. See more 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, … See more Cis-regulatory modules can be characterized by the information processing that they encode and the organization of their … See more The function of a gene regulatory network depends on the architecture of the nodes, whose function is dependent on the multiple cis-regulatory modules. The layout of cis-regulatory modules can provide enough information to generate spatial and … See more Besides experimentally determining CRMs, there are various bioinformatics algorithms for predicting them.

WebTransacting transcription regulators are proteins that can bind to cis-regulatory sequences located on different DNA molecules, and they can either activate or repress transcription. So, when a trans-acting transcription regulator is present and can bind to its cis-regulatory sequence, it can result in transcriptional regulation.
