ORTH
Orthology Ontology
The need of a common ontology for describing orthology information in biological research communities has led to the creation of the Orthology Ontology (ORTH). ORTH ontology is designed to describe sequence homology data available in multiple orthology databases on the Web (e.g.: OMA, OrthoDB, HieranoiDB, and etc.). By sequence homology data, we mostly mean gene region, gene and protein centric orthology, paralogy, and xenology information. Depending on the database, the homology information is structured in different ways.
