    Summary
    Enables rRNA (uridine-C5-)-methyltransferase activity and tRNA (uracil(54)-C5)-methyltransferase activity, S-adenosyl methionine-dependent. Predicted to be involved in rRNA methylation and tRNA processing. Located in mitochondrion. Is expressed in olfactory cortex ventricular layer and telencephalon ventricular layer. Orthologous to human TRMT2B (tRNA methyltransferase 2 homolog B). [provided by Alliance of Genome Resources, Dec 2024]

    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.
