Epitranscriptomics: Eukaryotic RNAs undergo a complex process of modification, which is indispensable for the normal function of cells. These RNA modifications encompass a wide array of chemical alterations, including methylation (e.g., N6-methyladenosine, m7G, m1A, Nm), deamination (e.g., I), acetylation (e.g., ac4C), and isomerization (e.g., Pseudouridine). Leveraging their unique chemical attributes, these modifications have the potential to regulate RNA properties such as stability, transcription, and translation, which exerts a profound influence on various cellular processes, including immune responses, phase separation, and embryonic cell division. Aberrations in modification distribution or extent have been associated with cellular malfunctions and human diseases. The collection of chemical marks that regulate gene expression is referred to as “epitranscriptomes”.
