The Molecular Interactions (MI) ontology forms a structured controlled vocabulary for the annotation of experiments concerned with protein-protein interactions. MI is developed by the HUPO Proteomics Standards Initiative.

Pattern for Local Unique Identifiers

Local identifiers in Molecular Interactions Controlled Vocabulary should match this regular expression:
^\d{4}$

Example Local Unique Identifier

0058   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Molecular Interactions Controlled Vocabulary should match this regular expression:
^mi:\d{4}$

Example CURIE

mi:0058

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 Molecular Interactions Controlled Vocabulary, the banana looks like MI:. Therefore, you may see local unique identifiers for this resource that look like MI:0058 (instead of the canonical form 0058) and CURIEs for this resource that look like mi:MI:0058 (instead of the canonical form mi:0058). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.

Publications

2004 The HUPO PSI's molecular interaction format--a community standard for the representation of protein interaction data.

The metaregistry provides mappings between the Bioregistry and other registries. There are 12 mappings to external registries for mi with 5 unique external prefixes.

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

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

Providers are various services that resolve CURIEs to URLs. The example CURIE mi:0058 is used to demonstrate the provides available for mi. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.

Additional providers curated in the Bioregistry are listed here.
