| Description: | PrOnto is a tool to query Gene Ontology term pair functional dissimilarity based on real biological data. GO terms that co-occur less than expected by chance in a species' annotations (annotation probabilities) or in its protein-protein interaction network (interaction probabilities) are considered functionally dissimilar. |

PrOnto database : GO term functional dissimilarity inferred from biological data. [PMID: 26089836]
Moonlighting proteins are defined by their involvement in multiple, unrelated functions. The computational prediction of such proteins requires a formal method of assessing the similarity of cellular processes, for example, by identifying dissimilar Gene Ontology terms. While many measures of Gene Ontology term similarity exist, most depend on abstract mathematical analyses of the structure of the GO tree and do not necessarily represent the underlying biology. Here, we propose two metrics of GO term functional dissimilarity derived from biological information, one based on the protein annotations and the other on the interactions between proteins. They have been collected in the PrOnto database, a novel tool which can be of particular use for the identification of moonlighting proteins. The database can be queried via an web-based interface which is freely available at http://tagc.univ-mrs.fr/pronto. |
