In the paper “Mitochondrial tRNA-lookalikes in nuclear chromosomes: Could they be functional?”¹ we discuss the possible functional roles of tRNA-lookalikes in the nuclear chromosomes. We also track the evolutionary history of the mitochondrial tRNA-lookalikes in nuclear chromosomes in 10 different species. The analysis was performed the same way as in our previous study², which can also be found here. The data can be downloaded by the following buttons:

File structure

For each organism, the list of tRNA-lookalikes is in tab-delimeted format. The columns are as follows:

• Column 1: Chromosome or scaffold
• Column 2: Strand
• Column 3: Start coordinate of the tRNA-lookalike, inclusive
• Column 4: End coordinate of the tRNA-lookalike, inclusive
• Column 5: Best-matched mitochondrial tRNA coordinates
• Column 6: Information about the mitochondrial tRNA (e.g. amino acid encoded)
• Column 7: Percentage identity of the best-matched tRNA sequence with the genomic sequence of the tRNA-lookalike
• Column 8: Number of mismatches between the sequence of the best-matched tRNA and the sequence of the tRNA-lookalike
