🧬 UniProt Proteins Scraper

🚀 Export UniProtKB protein records in seconds. Accessions, names, organisms, gene names, sequences, lengths, functions, and EC numbers — direct from the public UniProt REST API.

The UniProt Proteins Scraper turns the UniProtKB REST API public endpoint into a clean, structured dataset. It queries the source live, normalizes the response into one row per record, and pushes the result into an Apify dataset you can download or pipe to your warehouse.

All of UniProtKB Swiss-Prot and TrEMBL, hundreds of millions of protein records are covered in a single run, with stable field names and null-safe parsing.

🎯 Target Audience	💡 Primary Use Cases
🧬 Biologists	Snapshot the proteome of an organism
💊 Pharma	Cross-reference drug targets
🎓 Educators	Generate teaching datasets
🤖 ML teams	Train protein-language models

📋 What the UniProt Proteins Scraper does

• Calls the public UniProtKB REST API endpoint with the parameters you supply.
• Parses the response and flattens each record into a single dataset row.
• Casts numeric fields to numbers where applicable for clean spreadsheet imports.
• Surfaces rate-limit or upstream errors as a single-row error record instead of crashing.
• Exports to every Apify dataset format supported in the UI.

💡 Why it matters. The raw UniProtKB REST API response is great for API consumers but awkward for spreadsheets and BI tools. This actor normalizes the shape so the data drops straight into pandas, BigQuery, or a Google Sheet.

📊 Data fields

Each record includes: accession, ec, function, geneNames, keywords, length, organism, proteinName, references, results, scrapedAt, sequence. These field names come straight from the actor's dataset schema, so what you see here is what lands in your dataset.

⚠️ Good to Know. This actor calls the public UniProtKB REST API endpoint with no authentication required. Upstream rate limits apply; if the source returns a limit notice, you will see it as a single error record in your dataset.
