This genomic tRNA database contains tRNA gene predictions made by the program tRNAscan-SE 2.0 on complete or nearly complete genomes. Unless otherwise noted, all annotation is automated, and has not been inspected for agreement with published literature.

Inevitably with automated sequence analysis, we find exceptions to general identification rules, isoacceptor type predictions (esp. due to variable post-transcriptional anticodon modification), and questionable tRNA identifications (due to pseudogenes, SINES, or other tRNA-derived elements). We attempt to document all cases we come across, and welcome feedback (lowe @soe.ucsc.edu) on new or unrecognized discrepancies. For a more detailed description of the database, see the [User Guide].
