    Summary
    Enables tRNA 2'-phosphotransferase activity. Acts upstream of or within regulation of protein kinase activity and tRNA splicing, via endonucleolytic cleavage and ligation. Is expressed in several structures, including gonad; intestine; liver; lung; and spleen. Orthologous to human TRPT1 (tRNA phosphotransferase 1). [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.

      Status: VALIDATED

      Description
      Transcript Variant: This variant (2) lacks an alternate internal exon, compared to variant 1. This variant is represented as non-coding because the use of the supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
