What is protein localization?
If you want some insight as to the function of a protein its always a good idea to know where it is in your cell and when i.e. the proteins location. Most proteins have N-terminal sequences that, in one way or another, tells the cell where to send the proteins its just made. For example, the protein may be directed towards the cell membrane ready for secretion. Protein localization is generally a term used to refer to the study of where proteins are found within the cell. A common protein localization technique is to fuse a protein with a florescent amino acid sequence which the protein then drags about with it giving away its location to a florescent sensitive microscope. This can even be done in real time.
