Dockground: The Resource Expands to Protein-RNA Interactome

Area of Science:

• Structural Biology
• Computational Biology
• Molecular Biology

Background:

• RNA regulates cellular processes and binds proteins; dysregulation is linked to diseases like cancer.
• Characterizing protein-RNA interactions structurally is vital for understanding molecular mechanisms.
• RNA's flexibility complicates experimental structure determination, leading to a scarcity of available data.

Purpose of the Study:

• To expand the Dockground resource for computational modeling of protein-RNA interactions.

• To facilitate the development and benchmarking of structure-based modeling techniques for protein-RNA systems.

Main Methods:

• Extended the Dockground database to include protein-RNA interactions.
• Integrated new functionalities on the Dockground website (https://dockground.compbio.ku.edu/).
• Enabled searching by various criteria, including redundancy removal at different similarity thresholds.
• Implemented weekly updates with new structures from the Protein Data Bank.

Main Results:

• The Dockground resource now contains a dedicated dataset for protein-RNA interactions.
• The updated website offers enhanced search and data management capabilities.
• The database is regularly updated, ensuring access to the latest structural information.
• Facilitated computational modeling efforts by providing a valuable resource.

Conclusions:
