Intragenic promoter
WebAug 9, 2024 · Indeed, methylation of intragenic CGIs prevents promoter activity, and differential methylation can regulate transcription initiation in a tissue-specific and cell-type-specific manner in mammals 158. Webtype-specific intragenic enhancer is instrumental for B-cell-specific µ gene expression in mice, we wanted to determine whether enhancers, known to be associated with transcriptional activation, can confer chromatin ac-cessibility independent of the interaction with a RNA Pol II promoter. To this end, we introduced a gene con-

WebIn this paper, we present codon-restrained promoter silencing (CORPSE), a system for removing intragenic promoters. CORPSE exploits the DNA-σ factor structural relationship to disrupt σ70 promoters embedded within gene coding sequences with a minimum of synonymous codon changes. Web1 day ago · A. Schematic representations of the T-DNA constructs containing the native promoter of sense FLAIL (native-Pro) fused to the sense FLAIL DNA region with an NOS terminator as a terminator sequence or the native promoter of asFLAIL (anti-native-Pro) fused to the asFLAIL DNA region or a negative control with the 35S promoter (35S) …
WebApr 25, 2014 · Multiple protein isoforms produced by intragenic promoters in mouse brain. The mouse Shank3 gene has 22 exons that encode a synaptic scaffolding protein with five functional domains (Figure 1A). We have previously demonstrated that the Shank3 gene contains at least five intragenic promoters in humans and rodents which produce … WebCompetition experiments demonstrated that the intragenic promoters of the inactive genes were able to bind transcription factor(s), but not as efficiently as active genes. This …
WebDec 28, 2024 · The vast majority of eukaryotic transcription occurs in bursts during discrete periods of promoter activity, separated by periods of deep repression and inactivity. Elucidating the factors responsible for triggering transitions between these two states has been extremely challenging, partly due to the difficulties in measuring transcriptional … WebJan 19, 2024 · Future applications of synthetic biology will require refactored genetic sequences devoid of internal regulatory elements within coding sequences. These regulatory elements include cryptic and intragenic promoters, which may constitute up to a third of the predicted Escherichia coli promoters. The promoter activity is dependent on …
WebThe promoters of most class III genes include discontinuous intragenic structures, termed internal control regions (ICRs), that are composed of essential sequence blocks …
WebThese results indicate the existence of many intragenic promoters with generally low activity levels. Because a majority of the intragenic promoters are supported by C2 TSS tags (Figure 2b), most are considered to reflect actual transcriptional initiation events.
