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

The metaregistry provides mappings between the Semantic Farm and other registries. There are 4 mappings to external registries for this resource 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 Semantic Farm are listed here. These are typically inherited from Identifiers.org or Prefix Commons, and need extra curation.
