In the near future, salivary proteins may replace blood tests as a diagnostic tool. Researchers spend large amounts of time cataloguing “the complete salivary proteome”, which is a set of proteins in human saliva. Research in saliva proteomics and diagnostics is part of a nationwide effort to create a map of every human protein and every protein interaction, to see how they contribute to health and disease and how they act as markers for disease states. Following instructions encoded by genes, protein make up the body’s organs and regulate cellular processes. Defining exact protein pathways on a comprehensive level will enable the development of early diagnostic testing and precise drug design.
