VAST PROTEIN INTERACTIONS. “Proteins are the central players in interactomes. Most eukaryotic cells express several thousand proteins, and multicellular organisms commonly express tens of thousands of proteins, exponentially increasing the probable total number of macromolecular interactions in these organisms, all passing information on pathways linking each other throughout the cell. For example, analyses suggest on the order of 50,000 different protein interaction pairs, and perhaps four times more in humans.”
