Hypothesis

Can conserved protein interaction graphs and literature mining improve the prediction of protein functions?

Conclusion

The method developed is highly reliable for predicting gene ontology annotations for poorly characterized proteins.

Supporting Evidence

  • More than 80% of the GO annotations for proteins with highly conserved orthologs could be verified automatically.
  • All predictions were correct according to the verifications from a trained curator.
  • The method achieved 100% precision for the predicted GO annotations.

Takeaway

The researchers created a way to guess what proteins do by looking at how they interact with each other and what scientists have written about them.

Methodology

The study combined conserved protein interaction graphs with literature mining to predict protein functions.

Limitations

The method may not cover all proteins due to the limited availability of literature and the specificity of GO terms.
