Class-specific prediction of ncRNAs.

Area of Science:

• Genomics
• Bioinformatics
• Molecular Biology

Background:

• RNA families share sequence motifs and secondary structures, defining RNA classes like tRNAs, snoRNAs, and microRNAs.
• Detecting novel RNA members and annotating genomes comprehensively is complex, exceeding simple homology searches.

Purpose of the Study:

• To review available computational tools for identifying and annotating diverse RNA classes.
• To provide an overview of methods used in RNA family detection and genome annotation.

Main Methods:

• A three-tiered computational approach is typically used for RNA class detection.
• This involves an initial sensitive filter, followed by specific, computationally intensive methods, and finally, class-specific annotation and scoring.

Main Results:

• The review covers a diverse set of RNA classes.
• It highlights the tools currently available for each stage of the RNA detection and annotation pipeline.

Conclusions:

• Effective RNA class detection and genome annotation rely on sophisticated, multi-step computational strategies.
• Understanding the available tools is crucial for advancing genomic research and RNA biology.
