Profiling of RNA Structure at Single-Nucleotide Resolution Using nextPARS

Area of Science:

• Molecular Biology
• Genomics
• Bioinformatics

Background:

• RNA molecules are crucial for cellular processes, with their function dictated by sequence and structure.
• Understanding RNA secondary structure is essential for deciphering RNA function and evolutionary pathways.
• High-throughput sequencing-based RNA structure probing techniques enable transcriptome-wide structural analysis.

Purpose of the Study:

• To describe a computational protocol for nextPARS (parallel analysis of RNA structure).
• To enable the calculation of nextPARS scores for RNA structure determination.
• To utilize these scores for obtaining single-nucleotide resolution structural profiles of RNA sequences.

Main Methods:

• Development of a novel Illumina-based in vitro parallel probing method for RNA structure analysis (nextPARS).
• Description of a computational protocol for processing nextPARS data.
• Calculation of nextPARS scores to infer RNA structural states.

Main Results:
