The UniProt Reference Clusters (UniRef) provide clustered sets of sequences from the UniProt Knowledgebase (including isoforms) and selected UniParc records in order to obtain complete coverage of the sequence space at several resolutions while hiding redundant sequences (but not their descriptions) from view.

Pattern for Local Unique Identifiers

Local identifiers in UniRef should match this regular expression:
^UniRef(100|90|50)_([OPQ][0-9][A-Z0-9]{3}[0-9]|[A-NR-Z][0-9]([A-Z][A-Z0-9]{2}[0-9]){1,2}|UPI[A-F0-9]{10})$

Example Local Unique Identifier

UniRef90_P00750   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from UniRef should match this regular expression:
^uniref:UniRef(100|90|50)_([OPQ][0-9][A-Z0-9]{3}[0-9]|[A-NR-Z][0-9]([A-Z][A-Z0-9]{2}[0-9]){1,2}|UPI[A-F0-9]{10})$

Example CURIE

uniref:UniRef90_P00750

Mappings from records in Bioregistry to external registries comprises the metaregistry. This resource has 4 mappings to external registries with 3 unique external prefixes.

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 UniRef90_P00750 is used to demonstrate the providers available for UniRef. Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.

Additional providers curated in the Bioregistry are listed here. These are typically inherited from Identifiers.org or Prefix Commons, and need extra curation.
