GLOSSARY: Protein Expression and Production

Protein Expression and Production is a subcomponent of gene expression. It consists of the stages after DNA has been translated into polypeptide chains, which are ultimately folded into proteins. Protein expression is commonly used by proteomics researchers to denote the measurement of the presence and abundance of one or more proteins in a particular cell or tissue. Protein expression systems are very widely used in the life sciences, biotechnology and medicine. There are also significant medical applications for expression systems, notably the production of human insulin to treat diabetes.
