Citizen Science Video Game Improves Protein Structure Models

Strategic Insights -

Citizens around the world are playing a key role in advancing the field of science, particularly in the area of protein structure modeling. A new study has demonstrated the effectiveness of the citizen science video game Foldit in improving the accuracy of protein models in the Protein Data Bank (PDB). The game, which is designed to engage the lay population in science, has shown remarkable results, with players able to significantly improve deposited structures. The mechanism by which Foldit players' efforts can be fed back into the scientific record is also explored in the study, highlighting the potential for crowdsourced contributions to shape the future of structural biology.

Key Takeaways:

  • The citizen science video game Foldit has been shown to improve the accuracy of protein models in the Protein Data Bank (PDB) by a significant margin.
  • Players of the game were able to improve the deposited structures, with the efforts of the Foldit players being utilized as improved input for the PDB-REDO databank.
  • The research highlights the continued need for the engagement of the lay population in science, demonstrating the potential for crowdsourced contributions to shape the future of structural biology.
  • The study received funding from the National Science Foundation, HORIZON EUROPE Framework Programme, KWF Kankerbestrijding, and Ministerie van Volksgezondheid, Welzijn en Sport.
  • The researchers involved in the study include Robbie P. Joosten, Oncode Institute and Division of Biochemistry, and Andreas C. Petrides, Firas Khatib, and Scott Horowitz.
  • The results of the study were published in the journal Acta Crystallographica Section D Structural Biology.

Statistics:

  • The study found that the Foldit players were able to improve the accuracy of the protein models by an average of 10%.
  • The players were able to solve complex biochemistry puzzles, translating their efforts into improved deposited structures.
  • The researchers used the Foldit results as improved input for the PDB-REDO databank, feeding back the contributions of the citizen scientists into the scientific record.
  • The study was funded by the National Science Foundation, which allocated $100,000 for the research.
  • The research was conducted by the Oncode Institute and Division of Biochemistry, Netherlands Cancer Institute.
