Signal peptide Definition:
Polypeptides of proteins destined for the endomembrane system or for secretion are marked by a signal peptide, which targets the protein to the ER.

Signal peptide Notes:
A signal peptide is a short peptide present at the N-terminus of the majority of newly synthesized proteins that are destined towards the secretory pathway. These proteins include those that reside either inside certain organelles, secreted from the cell, or inserted into most cellular membranes. This signal basically guides the proteins towards its destination in the cell.
