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+$

Example Local Unique Identifier

000000024   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Protein Ontology should match this regular expression:
^pr:\d+$

Example CURIE

pr:000000024

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 14 mappings to external registries for pr with 4 unique external prefixes.

Providers are various services that resolve CURIEs to URLs. The example CURIE pr:000000024 is used to demonstrate the provides available for pr. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.

Additional providers curated in the Bioregistry are listed here.
