The Hierarchical Catalog of Eukaryotic Orthologs

OrthoDB presents a catalog of eukaryotic orthologous protein-coding genes. Orthology refers to the last common ancestor of the species under consideration, and thus OrthoDB explicitly delineates orthologs at each radiation along the species phylogeny. Available protein descriptors, together with Gene Ontology and InterPro attributes, serve to provide general descriptive annotations of the orthologous groups, and facilitate comprehensive database querying.
