GUUGle

GUUGle identifies potential RNA helical regions by finding exact complementary matches between a positive (target) and negative (query) sequence set under Watson-Crick and G-U wobble pairing rules.

Key Features:

• Efficient Helix Detection: Locates potential helical regions using Watson-Crick and G-U wobble base pairing rules.
• Sequence Set Analysis: Processes a positive sequence set (target) and a negative sequence set (query) to identify exact matches that conform to RNA base pairing rules and exceed a user-specified length threshold.
• Adaptability with Suffix Arrays: Can utilize precomputed suffix arrays for the positive sequence set to accelerate search operations on large datasets.
• Pre-filtering for Downstream Analyses: Serves as a preliminary filter to reduce candidate interactions for computationally intensive tasks such as miRNA target prediction.

Scientific Applications:

• miRNA Target Prediction: Narrows candidate miRNA–target interactions by identifying exact complementary matches under RNA base pairing rules between target and query sets.
• RNA Structure Analysis: Detects helical regions to support RNA secondary structure prediction and analysis.

Methodology:

Accepts a positive sequence set (target) and a negative sequence set (query), searches for exact matches that adhere to Watson-Crick and G-U pairing rules and exceed a user-defined length threshold, and can optionally use precomputed suffix arrays for the positive set to optimize searches.
