| abstractText | We have recently identified the first mammalian tRNA-specific adenosine deaminase human ADAT1, a member of the ADAR family of RNA editing enzymes. This protein is responsible for the first step of the unique A(37) to m(1)I(37) modification in eukaryotic tRNA(Ala). Here, we present the genomic structure of murine ADAT1 and the functional expression of mADAT1 cDNA. In mouse, as well as in human, ADAT1 is expressed from a single copy gene. The coding region of the mADAT1 gene is spread over nine exons, covering approximately 30kb of genomic DNA and encodes a protein of 499 amino acids. Overall, mADAT1 shares 81% nucleotide homology and 87.5% protein homology with the human ortholog. The recombinant mouse protein is active specifically and with a high efficiency on human tRNA(Ala) in vitro. Its genomic organization is compared to the structures of the sequence-related, pre-mRNA specific adenosine deaminases ADAR1 and ADAR2. |
