Imagine a protein that has been engineered to contain a nuclear localization signal, a nuclear export signal, a C-terminal perox
isomal targeting sequence, and a canonical endoplasmic reticulum (ER) signal sequence. With all of these signals, where would you expect to find the protein after its synthesis?
When the protein is made it will be able to target several organelles in the cell
However, the C-terminal sequence is the last sequence transcribed and when the protein is complete this sequence will be the sequence used for targeting the specific organelle
in this case, the C-terminal sequence targets the peroxisome
