Access Computed Structure Model Annotations
Access Gene Ontology terms (for Molecular Function, Cellular Component, and Biological Process), InterPro protein family classifications, and Pharos disease associations for a particular CSMs using the Annotation Tab.
RCSB.org offers access to >1 million Computed Structure Models (CSMs) from AlphaFoldDB and RoseTTAFold (from ModelArchive).
Only experimentally-determined PDB structures are included in search results by default. Move the "Include CSM" from gray- to cyan-colored slider to activate.
Users can now explore Computed Structure Models (CSMs) and their connections to GO terms for Molecular Function, Cellular Component, and Biological Process (from Gene Ontology), protein family classification (InterPro), and disease associations (Pharos). The inclusion of these external annotations expands the utility of studying CSMs at RCSB.org.
These annotations are accessible from the Structure Summary Annotations Tab for CSMs. For an example, see the Annotations Tab for the CSM of Alpha-enolase from AlphaFold.
Documentation is available about annotations for CSMs and PDB experimental data.
Developers: Switch to Sequence Coordinates Service by May 31, 2025
The new Sequence Coordinates Service supports better access to RCSB PDB features
A new Sequence Coordinates Service more effectively integrates the growing number of protein structures and introduces several minor API changes to better support access to RCSB PDB features.
The old 1D Coordinates Service API will remain operational for a limited period ending May 31, 2025.
Please contact RCSB PDB with any questions or concerns.
