DNA modification

Definition

Target type: biologicalprocess

The covalent alteration of one or more nucleotide sites in DNA, resulting in a change in its properties. [GOC:jl, GOC:ma]

DNA modification is a fundamental biological process that involves altering the chemical structure of DNA. This process is essential for various cellular functions, including gene regulation, DNA replication, and repair. There are two main types of DNA modifications: methylation and acetylation.

Methylation involves adding a methyl group (CH3) to a DNA base, typically cytosine. This modification can occur at specific sites within the genome, known as CpG islands, and is often associated with gene silencing. Methylation patterns are established and maintained by enzymes called DNA methyltransferases (DNMTs).

Acetylation, on the other hand, involves adding an acetyl group (COCH3) to a histone protein, which is a protein that helps package DNA into a compact structure called chromatin. Histones are involved in regulating gene expression by influencing the accessibility of DNA to transcription factors. Acetylation of histones typically leads to gene activation by making DNA more accessible. Acetylation is catalyzed by enzymes called histone acetyltransferases (HATs), while the removal of acetyl groups is carried out by histone deacetylases (HDACs).

DNA modifications can be influenced by various factors, including environmental exposures, lifestyle choices, and genetic predisposition. Changes in DNA modification patterns have been implicated in several diseases, including cancer and neurodevelopmental disorders.

In addition to methylation and acetylation, other types of DNA modifications include:

* **Phosphorylation:** Adding a phosphate group (PO4) to a DNA base or a histone protein. This modification can regulate DNA replication and repair.
* **Glycosylation:** Adding a sugar molecule to a DNA base. This modification can affect DNA stability and gene expression.
* **Ubiquitylation:** Adding a ubiquitin protein to a histone protein. This modification can regulate DNA repair and gene expression.

DNA modification is a dynamic process that plays a crucial role in shaping the genome and regulating gene expression. Further research is ongoing to understand the complex mechanisms underlying DNA modification and its implications for health and disease.'
