    Summary
    This gene encodes a protein responsible for the methylation of aspartic acid transfer RNA, specifically at the cytosine-38 residue in the anticodon loop. This enzyme also possesses residual DNA-(cytosine-C5) methyltransferase activity. While similar in sequence and structure to DNA cytosine methyltransferases, this gene is distinct and highly conserved in its function among taxa. [provided by RefSeq, Jun 2010]

    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.

    Suppressed Reference Sequence(s)

    The following Reference Sequences have been suppressed. Explain

    1. NM_176081.2: Suppressed sequence

      Description
      NM_176081.2: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.

    2. NM_176083.2: Suppressed sequence

      Description
      NM_176083.2: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.

    3. NM_176084.1: Suppressed sequence

      Description
      NM_176084.1: This RefSeq was permanently suppressed because it is a nonsense-mediated mRNA decay (NMD) candidate.

    4. NM_176085.1: Suppressed sequence

      Description
      NM_176085.1: This RefSeq was permanently suppressed because it is a nonsense-mediated mRNA decay (NMD) candidate.

    5. NM_176086.1: Suppressed sequence

      Description
      NM_176086.1: This RefSeq was permanently suppressed because it is a nonsense-mediated mRNA decay (NMD) candidate.
