Epitranscriptome modification involves the chemical modification of RNA molecules after transcription, a process that plays a crucial role in regulating gene expression and cellular function. The term epitranscriptome refers to the collection of all possible modifications that can occur to an RNA molecule, including the addition of various chemical groups to the nucleotides.

One of the most well-studied examples of epitranscriptome modification is the process of N6-methyladenosine (m6A) formation. In this process, a methyl group is added to the adenine base of adenosine residues within an mRNA molecule, altering its structure and function. The m6A modification has been shown to play a key role in the regulation of mRNA translation, splicing, and decay, and has been implicated in various diseases, including cancer.

Other types of epitranscriptome modifications include the addition of pseudouridine (ψ) and N1-methylguanosine (m1G). These modifications can also be found in various RNA molecules, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Epitranscriptome modifications can be reversed by specific enzymes, and the activity of these enzymes has been found to play a crucial role in regulating the epitranscriptome.

Research has shown that the epitranscriptome is dynamic and is influenced by various cellular processes, including transcription, translation, and splicing. The study of epitranscriptome modifications has the potential to reveal new insights into the regulation of gene expression and cellular function, and may provide new therapeutic targets for various diseases. Further research is needed to understand the full scope of epitranscriptome modifications and their impact on cellular function.
