Gene TM Ontology (GO) Consortium EMBL Outstation - European Bioinformatics Institute (EBI), Hinxton, Cambridge CB10 1SD, UK Jennifer I Clark Objectives: Build controlled vocabularies that allow researchers to describe gene products in a consistent way. 1) support the annotation of genomes, genes and gene products to these ontologies; 2) provide open and public access to the ontologies; 3) extend the community of people using GO. Ontologies defined (for our purposes) “an explicit specification of some topic” – Includes: Three ontologies in GO: Stanford Knowledge Systems Lab vocabulary of terms (names for concepts in molecular biology) defined logical relationships between the terms. The GO Consortium produces three ontologies covering the concepts that could be described as: •Molecular Function: elemental activity or task: DNA binding •Biological Process: broad objective or goal: mitosis, signal transduction. •Cellular Component: location or complex: nucleus, ribosome What’s in a GO term? term: transcription initiation id: GO:0006352 definition: Processes involved in starting transcription, the synthesis of RNA by RNA polymerases using a DNA template. The ontologies are used to record descriptions of gene products for diverse species. The gene products are electronically and then manually annotated to appropriate gene procucts: This annotation shows that HUCKLEBEIN protein is involved in the process of DNAdependent transcription. Term characteristics are inherited, so Transcription factor SL1 is understood also to be involved in DNA-dependent transcription and its parents. Consortium members Annotations are contributed by a growing number of biological database groups including: TIGR Rat Genome Database GeneDB S. pombe EBI GOA project The Arabidopsis Information Resource Berkeley Drosophila Genome Project The Institute for Genomic Research EBI Home Page http://www.ebi.ac.uk GO http://www.geneontology.org/ Email [email protected] • Open Source philosophy, making all products available free of charge. • The GO generates extraordinary cooperation between biologists from very diverse fields of study. Their commitment and focus has led to the development of a robust resource with the broadest application for the scientific community. Tools Annotation of gene products WormBase FlyBase DictyBase Genome Knowledge Base Mouse Genome Database The Zebrafish Information Network Saccharomyces Genome Database Major factors in the success of the GO: Gramene Compugen GeneDB for protozoa The consortium has made available free tools for browsing the GO. Amigo is a free, open source browser that has been created to display the GO and annotated gene products. The success of the GO Consortium’s work has been to demonstrate the great utility of shared community ontologies in the genomics community. This success has inspired the development of similar ontologies for other domains and has promoted open collaborations among groups working on similar projects such as anatomies. These developments are now being collected under the general umbrella of OBO (Open Biology Ontologies, http://www.geneontology.org/doc/gobo.HTML). Telephone Fax +44(0) 1223 492600 +44(0) 1223 494468
