Currently WormBase contains over 28,000 physical protein-protein interactions of which 1,500 protein-protein interactions have been curated by BioGRID as a collaboration with WormBase. Within the data set, over 17,000 protein-protein interactions are unique, and over 6,000 unique genes are involved in these interactions. In WormBase, protein-protein interaction data can be found as a subclass of physical interaction data in the ‘Interactions widget’ on the gene report page. The interactions widget provides all types of interaction data related to the gene of interest, such as physical, genetic, regulatory, and predicted interactions. Check out the micropublication ‘2018 Update on Protein-Protein Interaction Data in WormBase‘ by Jae Cho et al., and learn more about this data type in WormBase.
