Reversible RNA Modification N1-methyladenosine (m1A) in mRNA and tRNA

More than 100 modifications have been found in RNA. Analogous to epigenetic DNA methylation, epitranscriptomic modifications can be written, read, and erased by a complex network of proteins. Apart from N6-methyladenosine (m6A), N1-methyladenosine (m1A) has been found as a reversible modification in...
