Cis regulatory region
WebSep 5, 2011 · We aimed to take a computational approach to investigate candidate cis -regulatory elements (CREs) in a cluster of co-expressing genes in rice sperm cells. In this paper, we discuss the functions of these CREs in plant biology, including the regulation of cell cycle and reproductive development. A regulatory DNA sequence does not regulate unless it is activated. Different regulatory sequences are activated and then implement their regulation by different mechanisms. Expression of genes in mammals can be upregulated when signals are transmitted to the promoters associated with the genes. Cis-regulatory DNA s…

WebMar 13, 2002 · The noncoding region, or upstream regulatory region (URR), contains cis-enhancer elements to many cellular and viral factors. Binding of these factors to the URR modulates both viral replication and viral gene transcription . Binding sites have been identified for the viral proteins E1 and E2 ... WebAvian egg coloration is shaped by natural selection, but its genetic basis remains unclear. Here, we used genome-wide association analysis and identity by descent to finely map green egg colour to a 179-kb region of Chr4 based on the resequencing of 352 ducks (Anas platyrhynchos) from a segregating …
Cis-regulatory modules are one of several types of functional regulatory elements. Regulatory elements are binding sites for transcription factors, which are involved in gene regulation. Cis-regulatory modules perform a large amount of developmental information processing. 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 transcription factor binding sites. Additionally, cis-regulatory modules are also characterized by the way they affect the … See more The function of a gene regulatory network depends on the architecture of the nodes, whose function is dependent on the multiple cis … See more Besides experimentally determining CRMs, there are various bioinformatics algorithms for predicting them. Most algorithms try to search for significant combinations of transcription factor binding sites (DNA binding sites) in promoter sequences … See more The genome of an organism contains anywhere from a few hundred to thousands of different genes, all encoding a singular product … See more CREs have an important evolutionary role. The coding regions of genes are often well conserved among organisms; yet different organisms display marked phenotypic diversity. It has been found that polymorphisms occurring within non-coding sequences have a … See more Cis-regulatory modules can regulate their target genes over large distances. Several models have been proposed to describe the way that these modules may communicate with … See more WebApr 9, 2024 · cis- and transRegulators In addition to the three protein-coding genes, the lac operon contains short DNA sequences that do not encode proteins, but are instead binding sites for proteins involved in transcriptional regulation of the operon. In the lac operon, these sequences are called P (promoter), O (operator), and CBS (CAP-binding …
WebA key control point in regulating expression is the initiation of transcription, and much is known about how the transcription machinery assembles near the site of initiation and starts transcribing ( Luse, 2014; Robinson et al., 2016 ). WebCis -regulatory modules (CRMs) are DNA sequence elements that have transcriptional regulatory activity. Some CRMs are promoter sequences which bind the basal …
