UniProt is the world's leading high-quality, comprehensive and freely accessible resource of protein sequence and functional information.

The UniProt Knowledgebase (UniProtKB) is the central hub for the collection of functional information on proteins, with accurate, consistent and rich annotation. In addition to capturing the core data mandatory for each UniProtKB entry (mainly, the amino acid sequence, protein name or description, taxonomic data and citation information), as much annotation information as …

UniProt is the world's leading high-quality, comprehensive and freely accessible resource of protein sequence and functional information.

UniProt provides both sequence data and associated functional information, derived from a range of sources. More than 95% of the protein sequences provided by UniProtKB come from the translations of coding sequences (CDS) submitted to the ENA/GenBank/DDBJ nucleotide sequence resources of the International Nucleotide Sequence Database Collaboration (INSDC).

About. This SPARQL endpoint contains all UniProt data. It is free to access and supports the SPARQL 1.1 Standard.. There are 210,122,358,019 triples in this release (2025_01).

The UniProt Archive (UniParc) is a comprehensive and non-redundant database of protein sequences. These sequences are sourced from public sequence databases, and each unique sequence is stored in a UniParc entry with a stable unique identifier (UPI).

To explore and try out the ID Mapping services, please refer to: The ID Mapping website tool; Overview. The ID Mapping service can map between the identifiers used in one database, to the identifiers of another, e.g., from UniProt to Ensembl, or to PomBase, etc.
