YOGY is a web-based resource for retrieving orthologous proteins from ten eukaryotic organisms and one prokaryote: Homo sapiens, Mus musculus, Rattus norvegicus, Arabidopsis thaliana, Dictyostelium discoideum, Drosophila melanogaster, Caenorhabditis elegans, Plasmodium falciparum, Escherichia coli, Schizosaccharomyces pombe, and Saccharomyces cerevisiae. Using a gene or protein identifier from any of these organisms as a query, this database provides comprehensive, combined information on orthologs in other species using data from five independent resources: KOGs, Inparanoid, Homologene, OrthoMCL, and a table of curated orthologs between budding yeast and fission yeast.

Associated Gene Ontology (GO) terms of orthologs can also be retrieved for functional inference.
