Genes control the most basic functions of the cell, including what proteins to make and when. In 2003, the Human Genome Project created a draft map of our genes, and now researchers have completed a draft map of the human proteome—the set of all our proteins. The map, which includes proteins encoded by more than 17,000 genes as well as ones from regions of the genome previously thought to be non-coding, will help advance a broad range of research into human health and disease.
