Core Promoter Functions in the Regulation of Gene …

(3 days ago) Introduction. Transcriptional regulation of gene expression is critical for embryonic development (1,– 6).Multiple sequence-specific DNA binding transcription factors and co-regulators control gene expression (7,– 10), but the ultimate target of the transcription machinery is the initiation of transcription at the core promoter, which could hence be referred to as the …

The Core Promoter Is a Regulatory Hub for …

(1 days ago) In this mini-review, we focus on the role of the core promoter, particularly its downstream region, as the regulatory hub for developmental genes. The downstream core promoter element (DPE) was implicated in the control of evolutionarily conserved developmental gene regulatory networks (GRNs) governing body plan in both the anterior-posterior

Regulation of Gene Expression via the Core Promoter and …

(3 days ago) Introduction. The core promoter lies at the center of the transcription process, yet it is often an overlooked component in the regulation of gene expression (for reviews, see: Smale and Kadonaga, 2003; Thomas and Chiang, 2006; Heintzman and Ren, 2007; Juven-Gershon et al., 2008b).The core promoter is generally defined to be the DNA region that directs the …

Frontiers The Core Promoter Is a Regulatory Hub for …

(7 days ago) The development of multicellular organisms and the uniqueness of each cell are achieved by distinct transcriptional programs. Multiple processes that regulate gene expression converge at the core promoter region, an 80 bp region that directs accurate transcription initiation by RNA polymerase II (Pol II). In recent years, it has become apparent that the core …

9 - Promoter and Regulatory Element Prediction

(7 days ago) Second, the promoters and regulatory elements cannot be translated into protein sequences to increase the sensitivity for their detection. Third, promoter and regulatory sites to be predicted are normally short (six to eight nucleotides) and can be found in essentially any sequence by random chance, thus resulting in high rates of false

The core promoter: At the heart of gene expression - ScienceDirect

(1 days ago) The core promoter is best known for its role in directing proper transcription initiation at the TSS. Two modes of transcription initiation, focused and dispersed, were previously noted in metazoan (Fig. 1A) (reviewed in [6], [11]). Focused (also termed “sharp peak”) promoters contain a single predominant TSS or a few TSSs within a narrow

Identification and validation of promoters and cis-acting …

(7 days ago) Upstream of the core promoter region are the proximal and distal regions of promoters. Proximal and distal regions of the promoter contain different regulatory sequences such as enhancers, silencers, insulators, and cis-elements that contribute to the fine regulation of gene expression at the transcriptional level .The physical demarcation of the upstream regions …

(1 days ago) Cytosine methylation is important for transposon silencing and epigenetic regulation of endogenous genes, although the extent to which this DNA modification functions to regulate the genome is still unknown. Interestingly, genes methylated in transcribed regions are highly expressed and constitutively active, whereas promoter-methylated

Conserved noncoding transcription and core promoter regulatory …

(Just Now) Multicellular development is driven by regulatory programs that orchestrate the transcription of protein-coding and noncoding genes. To decipher this genomic regulatory code, and to investigate the developmental relevance of noncoding transcription, we compared genome-wide promoter activity throughout embryogenesis in 5 Drosophila species. Core promoters, …
