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

RDF Information

When using this resource in RDF, the following URI format should be used:

http://purl.uniprot.org/uniprot/$1

Providers

Providers are various services that resolve CURIEs to URLs. The example CURIE uniprot:P0DP23 is used to demonstrate the provides available for this resource. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
