    5. Data, including data from studies using mutant/knockout mice and cell lines from such mice, suggest that METTL2 and METTL6 (but not METTL8) contribute to post-transcriptional methylation of cytidine (formation of 3-methylcytidine) in tRNA; METTL2 methylates tRNA(Thr) and tRNA(Arg); METTL6 interacts with seryl-tRNA synthetase and methylates tRNA(Ser); METTL8 catalyzes post-transcriptional methylation of cytidine in mRNA.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
