Gene Ontology
The Gene Ontology project represents knowledge about gene functions across molecular, cellular, and tissue system levels.

About Gene Ontology
The Gene Ontology (GO) project is a major bioinformatics initiative that develops a computational, cross-species representation of knowledge about gene functions across molecular, cellular, and tissue system levels. It hosts the world’s largest public gene function knowledgebase, with data designed to be both human- and machine-readable for use in computational research. The resource provides GO ontology terms, traceable gene product annotations linked to scientific evidence, and GO Causal Activity Models (GO-CAMs) that link standard annotations into full biological system models. It also offers tools for browsing, searching, visualizing, and downloading data, plus a public API to integrate GO content into external research workflows.
