It began with the proteins. Before Watson and Crick unraveled DNA’s double helix in the 1950s, biochemists snipped, ground and pulverized animal tissues to extract and study proteins, the workhorses of the body.
Then, in 1990, the Human Genome Project launched. It promised to uncover the underpinnings of all human biology and the keys to treating disease. Funding for DNA and RNA tools and studies skyrocketed. Meanwhile, protein science fell behind.
While genomics unveiled a wealth of information, including the identity of genes that lead to disease when mutated, researchers still do not fully understand what all the genes really do and how mutations change their function and cause disease.
Now proteins are promising to provide the missing link. …
