Transcription Factors02:16

Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

RNA Polymerase II Accessory Proteins

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...

Eukaryotic Transcription Activators02:42

Eukaryotic Transcription Activators

Transcription activators are proteins that promote the transcription of genes from DNA to RNA. In most cases, these proteins contain two separate domains ‒ a domain that binds to DNA and a domain for activating transcription; however, in some cases, a single domain is responsible for both binding and activation of transcription, as seen in the glucocorticoid receptor and MyoD.
The binding domains are capable of recognizing and interacting with regulatory sequences on the DNA. These domains are...

Transcription

Overview
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
Transcription Can Produce Different Kinds...

Area of Science:

  • Developmental Biology
  • Genomics
  • Molecular Biology

Background:

  • Developmental processes rely on precise spatiotemporal gene expression for stereotyped embryonic patterning.
  • Recent genome-wide studies are reshaping our understanding of transcription factor (TF) roles in gene regulation.
  • Observed TF binding and RNA expression patterns sometimes appear to contradict the robustness of developmental outcomes.

Purpose of the Study:

  • To review current knowledge on transcription factor function in development.
  • To discuss how genomic and genetic studies inform our understanding of TF regulation.
  • To explore mechanisms conferring specificity and robustness to transcriptional regulation during embryogenesis.

Main Methods:

  • Review of recent genome-wide studies on transcription factor binding.
  • Analysis of RNA expression data in developmental contexts.
  • Integration of findings from genetic studies of transcription factor function.

Main Results:

  • Transcription factor regulation involves complex, cooperative interactions (direct and indirect).
  • Progressive priming of regulatory elements contributes to precise gene expression.
  • Multiple enhancers integrate activities to achieve specific and robust transcriptional outcomes.

Conclusions:

  • Developmental robustness arises from sophisticated transcriptional regulatory strategies.
  • Understanding TF function requires integrating genomic, genetic, and expression data.
  • Cooperative regulation, priming, and enhancer integration are key to precise developmental control.
