Reactome is an open-source database of curated biological pathways across species, offering pathway maps and enrichment tools to analyse gene lists in a pathway-focused context. It’s ideal for visualising data within established biochemical and cellular processes.
PANTHER performs overrepresentation tests across multiple databases; Gene ontology, reactome, PANTHER pathways and protein classes. Allows more control over the statistical test used and clearly summarises what was actually done.
Via its 'functional annotation' tool, DAVID allows you to calculate functional enrichment across a number of databases ; Gene Ontology, KEGG, reactome and others. Reliable, with a slightly clunky interface.
The core of reactome is the reactome pathways and browser. ALthough other tools use the reactome database, the reactome website provides a means to browse enrichment within the pathway browser view.
Biocyc is another suite of tools for enrichment and pathway browsing, which is particularly useful for prokaryotic work. It is licensed, but Monash does have a license.
STRING is not a functional enrichment tool, rather it is a convenient way to explore interactions within a genelist. Results are viewed as an interaction network. Best suited to smaller genelists.
Gene Ontology (GO) terms are the most widely use set of functional annotations, used by many enrichment tools. The gene ontology resource website itself provides several tools for browsing the GO term hierarchy.
A well known curated pathway database. It is used by many other tools but with a caveat - KEGG moved to a subscription model in 2011, and so enrichment tools need to use the last open release from 2011. However up to date KEGG pathways are browsable directly through their website.
The desktop-based GSEA tool is (one of many) gene set enrichment approaches. It uses of gene rankings across all genes rather than hypogeometric or fishers-exact tests of genelist enrichment. MSigDB (Molecular signatures database) is a suite of annotation databases suitable for GSEA analysis.
MetaboAnalyst is popular among the metabolomics community for statistical, functional and integrative analysis of metabolomics data. It has a feature called **Functional enrichment analysis**, which performs metabolite set enrichment analysis, metabolic pathway analysis, and pathway activity prediction from MS peaks.
Cytoscape is a desktop-based biological network analysis / visualization tool, rather than a functional enrichment tool (although plugins can change that). It is mentioned here because it is often useful as a next step when you need to create custom figures showing the interactions of an interesting biological pathway.
