Summary
Posttranslational modifications (PTMs) regulate gene transcription by altering histones and RNA polymerase II (RNAPII). This review details how PTMs on these key proteins control gene expression in yeast.
Area of Science:
- Molecular Biology
- Biochemistry
- Genetics
Background:
- Posttranslational modifications (PTMs) are crucial for protein function, influencing signaling, protein interactions, and cellular localization.
- Histones and RNA polymerase II (RNAPII) are key regulators of gene transcription.
- Understanding PTMs in gene regulation is vital for deciphering cellular processes.
Purpose of the Study:
- To review the fundamental characteristics of PTMs.
- To explore the specific roles of histone and RNAPII PTMs in gene transcription.
- To highlight the interplay between histone and RNAPII PTMs in the model organism Saccharomyces cerevisiae.
Main Methods:
- Literature review and synthesis of existing research.
- Focus on the model organism Saccharomyces cerevisiae for detailed analysis.
- Emphasis on mechanistic insights into PTM regulation of transcription.
Main Results:
- PTMs significantly impact histone structure and function, influencing chromatin accessibility.
- RNAPII undergoes various PTMs that modulate its activity during transcription.
- Interactions between histone and RNAPII PTMs create a complex regulatory network.
Conclusions:
- PTMs on histones and RNAPII are intricately linked to control gene transcription.
- These modifications provide a dynamic regulatory layer for gene expression.
- Further research into PTMs could reveal broader roles in cellular function and disease.

02:35Transcription 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 into a...

02:32Histone Modification
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 deacetylase,...

02:41Chromatin Structure Regulates pre-mRNA Processing
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.

02:36RNA 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...
