Human Gene TRDMT1 (uc001iop.3)
  Description: Homo sapiens tRNA aspartic acid methyltransferase 1 (TRDMT1), mRNA.
RefSeq Summary (NM_004412): 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]. Sequence Note: This RefSeq record was created from transcript and genomic sequence data to make the sequence consistent with the reference genome assembly. The genomic coordinates used for the transcript record were based on transcript alignments.

  ID: TRDMT_HUMAN
DESCRIPTION: RecName: Full=tRNA (cytosine(38)-C(5))-methyltransferase; EC=2.1.1.204; AltName: Full=DNA (cytosine-5)-methyltransferase-like protein 2; Short=Dnmt2; AltName: Full=DNA methyltransferase homolog HsaIIP; Short=DNA MTase homolog HsaIIP; Short=M.HsaIIP; AltName: Full=PuMet;
FUNCTION: Specifically methylates cytosine 38 in the anticodon loop of tRNA(Asp).
CATALYTIC ACTIVITY: S-adenosyl-L-methionine + cytosine(38) in tRNA = S-adenosyl-L-homocysteine + 5-methylcytosine(38) in tRNA.
SUBCELLULAR LOCATION: Nucleus (Probable).
TISSUE SPECIFICITY: Ubiquitous. Higher expression in testis, ovary and thymus and at much lower levels in spleen, prostate, colon, small intestine, and peripheral blood leukocytes.
SIMILARITY: Belongs to the C5-methyltransferase family.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
