GtRNAdb


tRNAscan-SE analysis of complete genomes


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

tRNA Gene Activity Predictions

Gene activity in 29 mammals including human and mouse were predicted using tRAP.
Details of the prediction method are available in the manuscript.
