tRNAviz

tRNAviz analyzes and visualizes transfer RNA (tRNA) sequence features across all domains of life to support comparative genomics and functional inference.

Key Features:

• Extensive Database Integration: Integrates over 150,000 tRNAs from organisms spanning Bacteria, Archaea, and Eukarya to provide a broad dataset for analysis.
• Consensus Sequence Feature Determination: Determines consensus sequence features across groups of tRNAs, including isotypes and isodecoders, to identify conserved and variable positions.
• Sequence Feature Distributions: Generates distributions of sequence features stratified by isotypes, clades, anticodons, and scores for comparative analyses.
• Visualization and Export: Produces visualizations representing consensus features and feature distributions and supports export of these visualization outputs.
• Comparative Genomics Analyses: Enables small- and large-scale comparative genomics analyses of tRNA sequences across taxa.

Scientific Applications:

• Translation and Non-translation Functions: Investigates how tRNA sequence variation impacts canonical roles in translation and non-translation-associated cellular functions.
• Evolutionary Analysis: Studies evolutionary conservation and variation of tRNA sequences across clades, isotypes, and isodecoders.
• Functional Genomics: Assesses the implications of tRNA sequence diversity for functional genomics and molecular genetics investigations.
• Comparative Sequence Analysis: Facilitates comparative analyses to infer structure–function relationships and evolutionary patterns among tRNAs.

Methodology:

Integrates extensive genomic tRNA data, determines consensus sequence features, and generates sequence feature distributions and visualizations based on biological properties such as isotype, clade, anticodon, and scores.
