Protein expression

Protein expression refers to the way in which proteins are synthesized, modified and regulated in living organisms. In protein research, this term can apply to either the object of study or the laboratory techniques required to manufacture proteins. Protein synthesis and gene expression are closely tied, as they are both stages in the process of genetic translation.

Overview

The process of protein expression involves the translation of genetic codes into proteins. This process begins with the transcription of DNA into mRNA, which is then translated into a protein. The protein can then undergo post-translational modifications before it becomes a fully functioning protein.

Protein Expression Systems

There are several types of protein expression systems used in research. These include bacterial expression systems, yeast expression systems, insect cell expression systems, and mammalian expression systems. Each system has its own advantages and disadvantages, and the choice of system depends on the type of protein being expressed and the intended use of the protein.

Applications

Protein expression has a wide range of applications in research and industry. It is used in the production of recombinant proteins for use in research and therapeutic applications. It is also used in the study of protein function and interaction, and in the development of new drugs and therapies.
