What Is Protein Expression?

The term "protein expression" is a little foreign to most people. This doesn't happen regularly in everyday life, so most people probably don't know what protein expression is or why it's important. In fact, this term can refer to two specifics, one fact which only adds to the potential for confusion.

Protein expression may be related to the research subject in a protein test or it may relate to actual laboratory techniques used to produce the protein. The meaning of this term depends on the context in which it is used. There are some sites from where you can get custom protein expression information for research like https://www.bosterbio.com/.


The use of protein depends on the actual needs of each cell. DNA is responsible for storing protein images, and RNA for messages is created to convert DNA messages into actual proteins. The word "transcription" is widely used in the world of protein expression and refers to the information passed from DNA to mRNA.

Transcription and translation processes

Each of these two processes has three steps: initiation, expansion, and cessation. The transcription part of the process begins with the development of DNA, which allows the RNA polymerase to bind. There are differences in transcription between eukaryotes and prokaryotes, especially the fact that prokaryotes do not require RNA modification. 

Move from

After the transcription and translation are complete, post-translation modifications can be made to better complement the structure created. This PTM can be used to add or change chemical structures, identify sites, or regulate activity within cells. For example, the formation or reduction of disulfide bridges would be the case for post-translational modification.
