The IntFOLD Integrated Protein Structure and Function Prediction Server
About the server
The IntFOLD server provides a unified interface for:
- Tertiary structure prediction/3D modelling
- 3D model quality estimates - with the option to refine/fix errors
- Intrinsic disorder prediction
- Domain prediction
- Prediction of protein-ligand binding residues

Case study
The animation below shows the top IntFOLD model for CSRP3 from mouse, which serves to demonstrate results from each of the integrated methods. Two globular zinc binding domains are linked by an intrinsically disordered region. The model helps us to understand how this protein might act as a stress sensor in cardiac myocytes.
