Database Description

The Gene Ontology Partition Database (GO PaD) contains data from an information theoretic analysis of the Gene Ontology (GO) that maximizes information content for gene enrichment and functional analysis. The GO Partition Database was designed to feature ontology partitions with GO terms of similar specificity. The GO partitions comprise varying numbers of GO nodes and present relevant information theoretic statistics, so researchers can choose to analyze gene datasets at arbitrary desired levels of specificity. The GO Partition Database features GO partitions for functional analysis of genes from human and ten other commonly-studied organisms, based on surveying nearly 132,000 genes. The database site ( also includes an online tutorial.
