The protein, in 3D.
What it does, what it treats, what it touches.
Type a UniProt ID (or pick a chip — insulin, p53, spike, hemoglobin). Spin the 3D structure. See diseases, drugs, and pathways in one card.
For curious patients, students, researchers, and people who read too many papers.

Where our answers come from
Curated open protein databases. Named sources.
UniProt
UniProt Consortium (CC-BY 4.0)
The definitive open protein knowledge base. 250 million+ entries, curated by a global team at EBI and SIB. Domain structure, function, localization, references, variants.
DrugBank + DGIdb
DrugBank / DGIdb
Drug-target interactions — which drugs target which proteins, linked from the UniProt entry.
DisGeNET + OMIM
DisGeNET / OMIM
Disease-gene associations. When a protein has a disease listed, it's from one of these curated databases.
Coming soon — AlphaFold
DeepMind AlphaFold DB
3D structure prediction for any UniProt protein. We'll wire up the viewer next.
Coming soon — ESMFold
Meta ESMFold
Fast structure prediction for custom sequences not in AlphaFold DB.
Coming soon — literature
NCBI PubMed
Recent paper abstracts mentioning a protein, aggregated from PubMed.
Questions
What's a UniProt ID?›
A unique 6-10 character code for each protein in the UniProt database (like P01308 for human insulin). You can also find proteins by name — just type 'insulin' or 'hemoglobin' to see candidates.
Do you show 3D structures?›
Not yet — that's Sprint 6B. We're integrating AlphaFold's prediction database (250M+ structures) so you can view the 3D shape of any protein.
Can I look up my own sequence?›
Not on the free landing — structure prediction (ESMFold) needs heavy compute and is coming in Sprint 6B. Today we look up proteins that are already in UniProt.
Where does 'targeted by drugs' come from?›
DrugBank + DGIdb curate these associations. A drug listed means there's at least one published pharmaceutical that binds the protein — not always for the indication you'd expect.
Is the data accurate?›
UniProt is the gold-standard curated resource for protein data. Each entry cites its primary literature. What you see on our card is a condensed summary — click through to UniProt for full detail.
What about non-human proteins?›
UniProt has proteins from all species — plants, bacteria, viruses. Type any UniProt ID, human or otherwise.
