2-methylthio-N6-isopentenyladenosine (mS2i6A) is a hypermodified modified nucleoside that has been shown to be present in mitochondrial tRNA. It reads codons starting with uridine. The mS2 group of mS2i6A is critical for the accurate decoding of Tyr and Phe codons. Higher concentrations of mS2i6A are found in tissues with a high energy demand, such as muscle and brain. One of the major role of mS2i6A is to stabilize the stacking interactions of the anticodon loop helix and thereby prevent codon misreading. Its deficiency has been linked to a higher rejection rate of tRNA4Leu by more aggressive proofreading on the wild-type ribosome. However, it is shown that mS2i6A has no effect on codon-anticodon interactions on wild-type ribosomes as long as aminoacyl-tRNA is in ternary complex with EF-Tu and GTP. Also, it has been reported that the lack of mS2i6A does not decrease the ability of the tRNA to be charged with its cognate amino acid, but it alters the efficiency with which the tRNA is bound to the ribosome. CDK5RAP1, which inhibits the activity of CDK5, is shown to be an N6-isopentenyladenosine methylthiotransferase. It converts the RNA modification N6-isopentenyladenosine (i6A) in mS2i6A post-synthetically. This conversion is observed both in the mitochondrial as well as nuclear RNA species.
