We are undoubtedly more than just our DNA sequence. But how much more? Although each cell in our body contains our genetic material, we are built out of proteins. Thus, understanding the proteome—more specifically, the variety of different proteomes within a single organism—is fundamental to fully elucidate biological function and dysfunction. In this poster, we have summarized and provided examples of some of the rich data housed in the Human Protein Atlas database, a comprehensive proteome database that sets a baseline for normal tissue as well as characterizing the proteomes of tissues in a diseased state. As data is added to such repositories, and more powerful computers are used to annotate and mine this data, scientists will gain a clearer sense of what the proteome can tell us and how this information can be used to improve human health and disease treatment.
