Signal peptides (SPs) are short amino acid sequences, typically found at the N-terminus of a protein, that act as molecular address labels. They direct proteins to specific cellular compartments or for secretion out of the cell. Without a functional signal peptide, many proteins would not reach their intended destinations, leading to cellular dysfunction. The accurate identification of signal peptides is therefore fundamental to numerous biological research areas, including protein production, vaccine development, and the study of genetic diseases.
