WormBase curates four different types of gene-to-gene interaction data: genetic, regulatory, physical, and predicted. These data are found in the interactions widget in each gene page. Aside from the predicted interactions, the other three types are curated with direct experimental evidence from the literature. Check out the micropublication which describes the Vennter tool. This tool is integrated into the interactions widget on WormBase gene pages and allows the visualization and analyses of interaction data.
