Definition

Proteomics (Twyman 2004; Mishra 2010) is the study of a proteome, that is, the ensemble of proteins produced by an organism, a system or its subpart, and of the interactions between proteins within the system. The most common use of the term refers to the study of a collection of proteins that vary with time and correspond to internal or external cell processes and modifications. Such changes may be reflected in the presence or absence of a protein, its expression level, and in a variety of post-translational modifications, such as phosphorylation, ubiquitination, methylation, acetylation, glycosylation, oxidation, or nitrosylation.

Common proteomics methods include the use of antibodies that recognize some proteins or protein classes, gel electrophoresis in two dimensions, shotgun proteomics, western blot, immunohistochemical staining, enzyme linked immunosorbent assay (ELISA), and mass spectrometry (MS).
