Defining Proteomics Branch of discovery science focusing on proteins a In 1994 defined as the complete set of proteins that is expressed and modified following expression by the entire genome in the lifetime of a cell. If we look at an organism it means that we are looking at the proteome of 3 trillion of cells and -1000 different cell types with different protein profiles a Can be more specific such as the complement of proteins expressed by a cell at any one time 1 Today proteomics is a scientific discipline that will bridge the gap between our understanding of genome sequences and cellular behavior 0/27/2005 Chaoqun Wu, Fudan University
