Spreading of Chromatin Modifications02:25

Spreading of Chromatin Modifications

9.9K
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.

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Base Excision Repair

27.6K
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.

Epigenetic Regulation

4.1K
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.

Background:

  • Understanding how epigenetic regulators target specific DNA sequences is crucial for deciphering gene regulation.
  • Histone modifications play a key role in controlling chromatin structure and gene expression.

Discussion:

  • The REF6 protein, a plant H3K27me3 demethylase, utilizes its zinc-finger domains to recognize a specific DNA motif.
  • This DNA binding event is essential for recruiting the SWI/SNF-type ATPase BRAHMA to target loci.

Key Insights:

  • Demonstrates a sequence-specific recruitment mechanism for chromatin-modifying complexes in plants.
  • Highlights the role of direct DNA binding by epigenetic regulators in targeting.

Outlook:

  • Further research can explore similar mechanisms in other epigenetic regulators across different species.
