Overview of Nucleotides Modifications

When it comes to the bio-molecular modifications, the first thing that comes to mind is the post-translational modification of proteins, which has been indicated to exert essential roles in a variety of signaling pathways, cellular activities, and many other biological functions. However, it has been found that post-translational modification is not only the “privilege” of proteins, but also occurs in other biomolecules in the organism, such as DNA and RNA. And post-transcriptional modification of RNA can enhance the stability of RNA structure, improve the efficiency of translation, and increase the structural and functional diversity of RNA.

RNA modification generally refers to the alterations (mainly addition and substitution) of chemical groups on four RNA bases and the ribose sugar moiety, leading to the secondary/tertiary structures and functions change of RNAs. Currently, there are at least 170 types of RNA modifications have been discovered in all living organisms. These modified RNAs are widely distributed in all kinds of RNAs, among which ribosomal RNA (rRNA) and transfer RNA (tRNA) are the most heavily modified. The base type, location, and quantity of the modifications all have an impact on the stability, activity, recognition, localization of RNAs, and they may also be related to some human diseases.

Custom Nucleotides Modification Services

Nucleotides modifications affect a diversity of biological processes in the organisms. For instance, modifications (commonly N⁶-methyladenosine) in messenger RNA (mRNA) regulate various aspects, such as mRNA location, metabolism, stability, protein translation, even stem cell differentiation. Chemical modifications in tRNA and rRNA directly affect protein translation. In humans, these diverse modifications in RNAs are closely linked to some human disorders, such as tumors and cancers, neurological disorders, mitochondrial-linked diseases, and diabetes.

All these properties and critical bio-functions endow the RNA modification of great potential to be a useful tool in laboratory analysis and therapeutics development. Firstly, the modified RNAs can be used for the control of gene expression and cell differentiation in epigenetics research, also can be utilized for RNA structure optimization. More importantly, the development of these nucleotides modifications or effective inhibitors holds great potential in human disease treatment.
