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:

Example Local Unique Identifier
000000024   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Protein Ontology should match this regular expression:

Example CURIE
MIRIAM Namespace Embedded in LUI
The legacy MIRIAM standard for generating CURIEs with this resource includes the namespaceEmbeddedInLUI as true. The actual part that gets prefixed before the local unique identifier regex, otherwise known as the banana, is PR:. Therefore, you might see local unique identifiers written out as CURIEs.
Metaregistry Protein Ontology

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.
