Logo for Protein Ontology 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+)?)$

Q15796-1   Resolve
A0A0G2QC33   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+)?)$

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.
