Co-activators and Co-repressors02:04

Co-activators and Co-repressors

7.2K
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...

Transcription Factors02:16

Transcription Factors

75.5K
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...

Combinatorial Gene Control02:33

Combinatorial Gene Control

8.3K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

RNA Polymerase II Accessory Proteins

9.1K
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...

Nucleosome Remodeling02:54

Nucleosome Remodeling

8.9K
Nucleosomes are the basic units of chromatin compaction. Each nucleosome consists of the DNA bound tightly around a histone core, which makes the DNA inaccessible to DNA binding proteins such as DNA polymerase and RNA polymerase. Hence, the fundamental problem is to ensure access to DNA when appropriate, despite the compact and protective chromatin structure.
Nucleosome remodeling complex
Eukaryotic cells have specialized enzymes called ATP-dependent nucleosome remodeling enzymes. These enzymes...

Cooperative Binding of Transcription Regulators02:13

Cooperative Binding of Transcription Regulators

6.3K
Transcriptional regulators bind to specific cis-regulatory sequences in the DNA to regulate gene transcription. These cis-regulatory sequences are very short, usually less than ten nucleotide pairs in length. The short length means that there is a high probability of the exact same sequence randomly occurring throughout the genome.  Since regulators can also bind to groups of similar sequences, this further increases the chances of random binding. Transcriptional regulators form...

Area of Science:

  • Molecular Biology
  • Genetics
  • Epigenetics

Background:

  • ATP-dependent chromatin remodeling complexes (SWI/SNF CRCs) are essential multiprotein machines that modify chromatin structure.
  • SWI/SNF CRCs regulate DNA accessibility for transcription factors (TFs), influencing gene expression.
  • These complexes are conserved across eukaryotes, with distinct subtypes in humans (cBAF, pBAF, ncBAF) and Arabidopsis (SAS, MAS, BAS).

Purpose of the Study:

  • To highlight the critical interplay between SWI/SNF CRCs and TFs in both human and plant systems.
  • To summarize recent findings on the roles of SWI/SNF CRCs and TFs in regulating key biological processes.
  • To discuss potential mechanisms underlying TF and SWI/SNF CRC-mediated transcriptional control.

Main Methods:

  • Literature review and synthesis of recent research findings.
  • Comparative analysis of SWI/SNF CRCs and TF interactions in humans and Arabidopsis.
  • Discussion of proposed molecular mechanisms.

Main Results:

  • SWI/SNF CRCs and TFs engage in crucial interactions that govern gene expression.
  • Arabidopsis provides a valuable model for uncovering evolutionarily conserved SWI/SNF-TF interactions.
  • Specific SWI/SNF CRC subtypes, TF types, and cellular contexts influence interaction specificity.

Conclusions:

  • The interplay between SWI/SNF CRCs and TFs is fundamental for transcriptional regulation.
  • Further research into SWI/SNF-TF interactions, considering subtype and context, is needed to understand specificity and regulatory events.
  • Arabidopsis research can illuminate conserved mechanisms of chromatin remodeling and gene regulation.
