WDSPdb: an updated resource for WD40 proteins.

Area of Science:

• Biochemistry and Molecular Biology
• Structural Biology
• Bioinformatics

Background:

• WD40-repeat proteins are crucial scaffold molecules involved in diverse cellular processes.
• Understanding their structure is essential for elucidating protein-protein interactions and complex assembly.
• Existing resources may lack comprehensive structural and variant data for this protein family.

Purpose of the Study:

• To present WDSPdb 2.0, a substantially updated database of WD40-repeat proteins.
• To provide accurate secondary and tertiary structure predictions and featured site annotations.
• To integrate a wide range of genetic and protein interaction variant data.

Main Methods:

• Development of an optimized computational pipeline for structure prediction.
• Integration of data from multiple public databases including ClinVar, Cosmic, and IntAct.
• Enhancement of web interface for improved data visualization and exploration.

Main Results:

• WDSPdb 2.0 contains approximately 600,000 entries, a tenfold increase.
• The database integrates over 37,000 variants from diverse sources.
• Significant improvements in web-based visualization, exploration, and data downloading capabilities.

Conclusions:

• WDSPdb 2.0 is a vastly expanded and improved resource for studying WD40-repeat proteins.
• The integrated structural and variant data facilitates research into protein function and disease association.
• Enhanced usability empowers researchers to explore complex protein interactions more effectively.
