Friendster for Proteins

The body contains 25,000 genes, which can form as many as 1 million proteins interacting in hundreds of millions of ways. Perhaps only 5% to 10% of all protein and gene interactions have been documented so far. Network biologists' ultimate aim, still a decade away, is to create computer programs that could simulate the effects of drugs on cells in the same way that Boeing simulates a new jetliner before it flies.

It is only within the past ten years that a new array of high-speed genetic tools has made network maps possible, by allowing researchers to look at thousands of genes or proteins at once and measuring how they interact. Then researchers can go back to cells or animals to test whether the predictions hold true.
