Transcription Elongation Factors

Transcription elongation is a dynamic process that alters depending upon the sequence heterogeneity of the DNA being transcribed. Hence, it is not surprising that the elongation complex's composition also varies along the way while transcribing a gene.
The transcription elongation is regulated via pausing of RNA polymerase on several occasions during transcription. In bacteria, these halts are necessary because the transcription of DNA into mRNA is coupled to the translation of that mRNA...

Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

Histone Modification

16.8K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone...

Area of Science:

  • Bioinformatics
  • Genomics
  • Molecular Biology

Background:

  • Gene Ontology (GO) annotations traditionally have limited specificity due to their legacy format.
  • The original GO annotation format primarily captured gene product roles or locations, with limited contextual information.
  • There was a need to enhance GO annotations to include more physiologically relevant details.

Purpose of the Study:

  • To introduce and explain the utility of "annotation extensions" in the GO annotation format.
  • To demonstrate how annotation extensions provide valuable contextual detail for GO terms.
  • To highlight the benefits of enhanced GO annotations for scientific analysis.

Main Methods:

  • Introduction of a new field, "annotation extensions," into the GO annotation file format.
  • Utilizing experimentally verified links between gene products and physiological information.
  • Providing examples to illustrate the usage and benefits of annotation extensions.

Main Results:

  • Annotation extensions allow for the capture of detailed contextual information previously unavailable.
  • This new field enables more accurate analysis of pathway and network data.
  • Experimentally verified links can now be explicitly represented.

Conclusions:

  • Annotation extensions significantly increase the expressivity and specificity of GO annotations.
  • This advancement is crucial for accurate pathway and network data analysis.
  • The enhanced GO format benefits both scientists and bioinformaticians by providing richer biological insights.
