RNA Polymerase II Accessory Proteins02:36

RNA Polymerase II Accessory Proteins

8.9K
Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...

Regulation of Expression at Multiple Steps

1.4K
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

Co-activators and Co-repressors

7.0K
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

Regulation of Expression Occurs at Multiple Steps

20.2K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

Area of Science:

  • Genomics
  • Molecular Biology
  • Epigenetics

Background:

  • The human genome extensively transcribes noncoding RNAs, greatly outnumbering protein-coding genes.
  • Long noncoding RNAs (lncRNAs) are established regulators of gene expression, development, and disease.
  • Enhancers, key regulatory elements, are now known to produce enhancer-derived RNAs (eRNAs).

Purpose of the Study:

  • To review emerging evidence on the functional roles of enhancer-derived RNAs (eRNAs).
  • To explore the potential mechanisms by which eRNAs influence gene expression.
  • To contextualize eRNA function within the broader landscape of noncoding RNA (ncRNA) roles.

Main Methods:

  • Literature review of recent studies on eRNAs and ncRNAs.
  • Analysis of experimental evidence linking eRNAs to enhancer activity.
  • Discussion of proposed molecular mechanisms for eRNA function.

Main Results:

  • Growing evidence indicates that eRNAs contribute to enhancer function.
  • Specific eRNAs are associated with the regulation of target gene expression.
  • Potential mechanisms include acting in cis or trans to modulate chromatin and transcription.

Conclusions:

  • eRNAs represent a significant class of functional ncRNAs.
  • Understanding eRNA function provides new insights into gene regulation.
  • Further research is needed to fully elucidate the diverse roles of eRNAs in biological processes and disease.
