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
