Loading Python runtime (first visit about 10–20 s)…
Load a protein
Downloads the canonical sequence as FASTA from
rest.uniprot.org. Isoforms work too (e.g. P04637-2).
UniProt examples
Digits, spaces and * are removed and letters are upper-cased.
A UniProt-style header fills in accession, gene and organism.
Link to a view (URL parameters)
Add these to the page URL (after ?, joined with &) to open a protein and view directly.
The address bar is updated as you work, so you can copy it to share the current view.
| Parameter | Meaning |
|---|---|
| accession, id | Fetch this UniProt record (e.g. P68871 or HBB_HUMAN). |
| sequence | Load a plain or FASTA sequence instead of fetching. |
| tab | Open a tab: seq, comp, prop, digest, sites, raw. |
| enzyme | Digest enzyme (e.g. trypsin, lys_n, elastase), or custom together with customRegex. |
| missed | Allowed missed cleavages (0–10). |
| minLen, maxLen | Peptide length bounds (residues). |
| minMass, maxMass | Peptide monoisotopic mass bounds (Da). |
| semi | 1 for semi-specific digestion. |
| scale, window | Property tab scale (e.g. hphob_kyte_doolittle) and window size (1–99 residues). |
Example: ?accession=P68871&tab=digest&enzyme=trypsin&missed=2
