What you can do with it
Experimental vs predicted
The default PDB entry, chosen by how much of the protein it resolves and at what resolution, beside the AlphaFold DB model; a picked residue follows each source's available correspondence.
Confidence (pLDDT)
Source-model pLDDT colours stay on the model, while the UniProt track and range means use only unique exact residue matches, with missing scores omitted and contributing counts shown.
Sequence tracks
Domains, sites, modifications, topology, structural coverage across every entry, confidence and variants on one zoomable ruler that works from the keyboard.
Drugs and targets
Every drug and clinical candidate whose curated mechanism names the target, from Open Targets, with its stage, withdrawals and indications.
Variants and AlphaMissense
UniProt's curated variants at once, the EBI Proteins API's full list on request with its size shown first, and AlphaMissense scores as an optional track.
Residue-level mapping
Experimental selections use the loaded file’s residue-level SIFTS record checked against current UniProt, showing exact observed residues and qualified annotated substitutions while keeping withheld or unmapped positions explicit.
Links across the suite
A drug name opens in the molecule app and an indication opens as a trial landscape in the pipeline app.
Sources and exports
Each panel names its source and, where the provider reports one, its release or data version, and the exports (PDB entries, drugs and annotations as CSV, the sequence as FASTA, the map, tracks and 3D views as figures) carry their sources, licences and retrieval times inside the file.

Where it runs and what it sends
Public data hosts declared for this app: rest.uniprot.org, www.ebi.ac.uk, data.rcsb.org, models.rcsb.org, alphafold.ebi.ac.uk and api.platform.opentargets.org.
Anything in the address bar before the # (a search, a SMILES, an accession or a step) is sent to this site's host when a page loads or a link is opened; anything after the # is not sent.
Not used, by licence:
- COSMIC. Its use in a commercial product or a public website needs a commercial licence, so COSMIC-only variant records are left out.
- DrugBank. Its licence is non-commercial; drug data comes from Open Targets instead.
- KEGG. Non-academic use needs a commercial licence.
- OMIM. Commercial use needs a licence.
- AlphaFold 3 outputs. Their terms allow non-commercial use only; predicted models come from AlphaFold DB (CC BY 4.0).
