Proteomics

7.7K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Summary

Enzyme activity assays complement difference gel electrophoresis (DIGE) proteomics. Enzyme testing validates experimental systems, corroborates DIGE findings on differential protein expression, and supports metabolic change data.
