Knowledge of the biological role of proteins in one organism can often be transferred to other organisms. The goal of the Gene Ontology Consortium is to produce a dynamic, controlled vocabulary that can be applied to all eukaryotes even as knowledge of gene and protein roles in cells is accumulating and changing.
GO Objectives Provide a controlled vocabulary for the description of third independent “ontologies”: molecularfunction and cellular component of gene products, as well as the biologicalprocess representing the gene product’s higher order role. Use these terms as attributes of gene products in the collaborating databases. (gene product associations). Allow queries across databases using GO terms, providing linkage of biological information across species, maintain history and dynamic linkage.
GO = Three Ontologies • Biological Process = goal or objective within cell • Molecular Function = elemental activity or task • Cellular Component= location or complex
