The PRotein Ontology (PRO) has been designed to describe the relationships of proteins and protein evolutionary classes, to delineate the multiple protein forms of a gene locus (ontology for protein forms), and to interconnect existing ontologies.

Pattern for Local Unique Identifiers

Local identifiers in Protein Ontology should match this regular expression:
^(?:\d{9}|[OPQ][0-9][A-Z0-9]{3}[0-9](?:-\d+)?|[A-NR-Z][0-9](?:[A-Z][A-Z0-9]{2}[0-9]){1,2}(?:-\d+)?)$

Example Local Unique Identifiers

000000024   Resolve
P0DP23   Resolve
Q15796   Resolve
Q15796-1   Resolve
A0A0G2QC33   Resolve
A0A0G2QC33-2   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Protein Ontology should match this regular expression:
^PR:(?:\d{9}|[OPQ][0-9][A-Z0-9]{3}[0-9](?:-\d+)?|[A-NR-Z][0-9](?:[A-Z][A-Z0-9]{2}[0-9]){1,2}(?:-\d+)?)$

Example CURIEs

PR:000000024
PR:P0DP23
PR:Q15796
PR:Q15796-1
PR:A0A0G2QC33
PR:A0A0G2QC33-2

MIRIAM Namespace Embedded in LUI

The legacy MIRIAM standard for generating CURIEs with this resource annotates the namespaceEmbeddedInLUI as true. This means that you may see local unique identifiers that include a redundant prefix and delimiter (also known as a banana) and therefore look like a CURIE. For Protein Ontology, the banana looks like PR:. Therefore, you may see local unique identifiers for this resource that look like PR:000000024 (instead of the canonical form 000000024) and CURIEs for this resource that look like PR:PR:000000024 (instead of the canonical form PR:000000024). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.

The metaregistry provides mappings between the Bioregistry and other registries. There are 15 mappings to external registries for this resource with 5 unique external prefixes.

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

http://purl.obolibrary.org/obo/PR_$1

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 000000024 is used to demonstrate the providers available for Protein Ontology. 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.
