The UniProt Knowledgebase (UniProtKB) is a comprehensive resource for protein sequence and functional information with extensive cross-references to more than 120 external databases. Besides amino acid sequence and a description, it also provides taxonomic data and citation information.

Pattern for Local Unique Identifiers

Local identifiers in UniProt Protein should match this regular expression:
^([A-N,R-Z][0-9]([A-Z][A-Z, 0-9][A-Z, 0-9][0-9]){1,2})|([O,P,Q][0-9][A-Z, 0-9][A-Z, 0-9][A-Z, 0-9][0-9])(\.\d+)?$

Example Local Unique Identifier
P0DP23   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from UniProt Protein should match this regular expression:
^uniprot:([A-N,R-Z][0-9]([A-Z][A-Z, 0-9][A-Z, 0-9][0-9]){1,2})|([O,P,Q][0-9][A-Z, 0-9][A-Z, 0-9][A-Z, 0-9][0-9])(\.\d+)?$

Example CURIE
uniprot:P0DP23

Providers

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier P0DP23 is used to demonstrate the providers available for UniProt Protein. A guide for curating additional providers can be found here.
