RPpocket

RPpocket analyzes RNA-protein complex structures to characterize pocket topology and structural determinants of RNA-protein recognition.

Key Features:

• Curated dataset: Contains a curated dataset of 793 pockets extracted from 74 non-redundant RNA-protein complex structures.
• Pocket extraction: Extracts pockets from RNA-protein complex structures for structural analysis.
• Binding vs non-binding comparison: Analyzes and compares topological properties of binding and non-binding pockets.
• Topology characteristics: Reports that binding pockets tend to be more extended than non-binding pockets.
• Force contribution analysis: Assesses the predominance of long-range forces in initial recognition and the role of short-range forces in stabilization and optimization of interactions.
• Sequence and secondary structure annotation: Provides detailed sequence, secondary structure, and pocket topology information for each pocket.

Scientific Applications:

• Mechanistic studies: Enables investigation of structural mechanisms underlying RNA-protein recognition and interaction.
• RNA-protein engineering: Supports RNA-protein engineering by supplying pocket topology, sequence, and secondary structure data relevant to design.
• Therapeutic development: Informs development of therapeutic strategies by characterizing pocket properties relevant to molecular recognition.
• Comparative structural analysis: Facilitates identification of determinants of binding through comparison of binding and non-binding pockets.

Methodology:

Pockets were extracted from 74 non-redundant RNA-protein complex structures to compile a curated dataset of 793 pockets, followed by comparative topological analysis of binding versus non-binding pockets and assessment of long-range versus short-range force contributions.
