Human protein-protein interaction network

Dataset information

This is protein-protein interaction network that contains physical interactions between proteins that are experimentally documented in humans, such as metabolic enzyme-coupled interactions and signaling interactions. Nodes represent human proteins and edges represent physical interaction between proteins in a human cell.
