Insights

Alternative splicing of epigenetic reader proteins significantly impacts gene regulation and cancer development. Understanding these splicing events offers new avenues for precision oncology and targeted cancer therapies.

Area of Science:

  • Molecular Biology
  • Genetics
  • Epigenetics

Background:

  • Epigenetic reader proteins regulate gene expression by interacting with chromatin modifications.
  • Alternative splicing generates diverse protein isoforms with potentially altered functions.
  • Dysregulation of epigenetic readers and alternative splicing is implicated in cancer etiology.

Purpose of the Study:

  • To review the role of alternative splicing in epigenetic reader protein functionality.
  • To explore the contribution of epigenetic deregulation and splicing to pathophysiology.
  • To provide an A-Z guide of epigenetic readers, highlighting isoform-specific functions.

Main Methods:

  • Literature review focusing on epigenetic readers and alternative splicing.
  • Analysis of 'yin-yang' roles of full-length versus spliced isoforms.
  • Discussion of clinical implications and therapeutic potential.

Main Results:

  • Epigenetic readers are crucial for transcriptional regulation, development, and cancer.
  • Alternative splicing creates antagonistic roles for different protein isoforms.
  • Deregulation of these processes contributes to disease pathophysiology.

Conclusions:

  • Alternative splicing of epigenetic readers is fundamentally important in biological processes and disease.
  • Further research is needed to understand the functional diversity and regulatory mechanisms.
  • Targeting alternatively spliced epigenetic readers holds promise for precision oncology.

Alternative RNA Splicing02:18

Alternative RNA Splicing

Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

RNA Splicing01:32

RNA Splicing

Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

Spreading of Chromatin Modifications02:25

Spreading of Chromatin Modifications

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.

Epigenetic Regulation01:37

Epigenetic Regulation

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.

Histone Variants at the Centromere02:30

Histone Variants at the Centromere

Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

Chromatin Structure Regulates pre-mRNA Processing02:41

Chromatin 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.
The chromatin structure, especially...
