How this service works

UniProt reviewed (Swiss-Prot) human protein entries for a gene symbol: accession, protein name, gene, sequence length and the curated function summary. Human only (taxon 9606). Up to 5 entries per call.

Output

Returns a JSON object containing the queried gene symbol, the UniProt source URL, and an array of entries. Each entry includes the UniProt URL, gene symbol, amino acid sequence length, a function description (with PubMed citations), organism (e.g. Homo sapiens), UniProt accession ID, and protein name. Also includes a checkedAt timestamp.

Example use cases

Cancer gene protein lookup

“What protein does the BRCA2 gene encode, and what is its biological function according to UniProt? Give me the accession number too.”

Drug target research

“I'm researching EGFR as a drug target — can you pull the UniProt protein entry for the EGFR gene and tell me what it does and how long the protein is?”

Multi-entry gene annotation

“Fetch up to 3 UniProt protein entries for the KRAS gene so I can see all annotated isoforms and their functions.”

Endpoint

GEThttps://api.healthtravel-api.workers.dev/api/health/uniprot-protein-knowledge?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need structured protein annotation data (function, accession, organism, length) for a specific human gene symbol, sourced directly from UniProt's authoritative knowledgebase, without needing a signup or API key. Prefer it over raw UniProt API calls when you want a pay-per-use, zero-setup integration with normalized JSON output. Not suitable for non-human organisms or bulk proteome queries.

Side effects

Gene symbol not found in UniProt — returns empty entries array
Invalid gene symbol format (too short, too long, or illegal characters) — returns validation error
max parameter out of range (must be 1–5) — returns error
UniProt upstream service unavailable — returns 5xx or timeout
Payment failure — call is not charged and returns 402
