The protein interaction part of the integrated network is available for download. Due to several licensing issues, we are not allowed to release the complete integrated network (including signaling, metabolism and gene regulation).
Rows with one protein only describe self-interactions, and rows with more than two proteins describe complex interactions. In cases when proteins are annotated only with genomic identifiers but no protein identifiers in the according source databases, and if the genomic identifiers map to more than one UniProt entry, the according UniProt entry names are concatenated (e.g. RL40_HUMAN.RS27A_HUMAN.UBIQ_HUMAN) as it is unclear which of the gene products interact.
