ABSTRACT
Proteomics is the study of “the entire protein complement expressed by a genome in a cell or tissue type” (Pandey and Mann, 2004). Proteomics now covers all aspects of protein research in a cell, encompassing the abundance and changes in time and biological behavior, as well as posttranslational modications (PTMs) related to the biological functions and protein-protein interactions. Proteomics has become the crucial element of “omic” approaches or system biology tools, and is contributing to a new understanding of biological systems.
