The TRDMT1 (tRNA aspartic acid methyltransferase 1) recombinant protein is derived from the human TRDMT1 gene, which encodes an enzyme belonging to the RNA methyltransferase family. Originally misclassified as a DNA methyltransferase (DNMT2), TRDMT1 was later found to specifically catalyze the methylation of tRNA molecules, particularly modifying cytosine residues at position 38 (C38) in the anticodon loop of tRNAAsp. This post-transcriptional modification enhances tRNA stability, ensures translational fidelity, and participates in cellular stress responses. TRDMT1 is evolutionarily conserved across eukaryotes and has been implicated in diverse biological processes, including viral defense mechanisms, epigenetic regulation, and stress granule formation.
The recombinant TRDMT1 protein is typically produced using heterologous expression systems (e.g., E. coli or mammalian cells) to enable large-scale purification while retaining enzymatic activity. Its production facilitates biochemical and structural studies, allowing researchers to investigate substrate specificity, catalytic mechanisms, and interactions with RNA substrates or regulatory proteins. TRDMT1’s role in diseases remains under exploration, though preliminary studies suggest potential links to cancer progression, neurological disorders, and viral infections. For instance, TRDMT1-mediated tRNA methylation may influence viral replication cycles by modifying host or viral RNA.
Research applications of the recombinant protein include in vitro methylation assays, inhibitor screening for therapeutic development, and structural analyses (e.g., X-ray crystallography) to resolve its catalytic domain architecture. Recent advances also explore its utility in synthetic biology for engineering modified tRNA systems. Despite progress, questions persist regarding its tissue-specific regulation, non-tRNA substrates, and broader functional impact on cellular RNA landscapes. The availability of recombinant TRDMT1 continues to drive mechanistic insights into RNA epigenetics and its biomedical implications.
