lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

10.2K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Epigenetic Regulation

4.2K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Spreading of Chromatin Modifications

10.0K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Area of Science:

  • Molecular Biology
  • Epigenetics
  • Genomics

Background:

  • Epigenetic modifying factors control chromatin structure and gene expression during development.
  • These factors involve protein complexes with non-canonical RNA-binding components.
  • Interactions with long non-coding RNAs (lncRNAs) are increasingly recognized in epigenetic regulation.

Purpose of the Study:

  • To review epigenetic factors interacting with lncRNAs in mammals.
  • To discuss challenges in understanding the role of lncRNAs in epigenetic networks.
  • To highlight the necessity of integrated protein and RNA-centric approaches.

Main Methods:

  • Literature review of epigenetic modifying factors and lncRNA interactions.
  • Analysis of studies reporting protein-lncRNA interactions in mouse and human.
  • Synthesis of current understanding and future research directions.

Main Results:

  • Numerous epigenetic modifying factors have been identified to interact with lncRNAs.
  • These interactions often occur without clear sequence or structural signatures.
  • Evidence supports the in vivo role of protein-lncRNA interactions in shaping the epigenetic landscape.

Conclusions:

  • Protein-lncRNA interactions are integral to epigenetic regulation.
  • Further research is needed to fully elucidate these complex networks.
  • Combined protein and RNA-based methodologies are essential for advancing the field.
