Protein tags and modifiers are short peptide sequences cloned in frame with protein coding sequences that change the protein's behavior.
Protein tags and modifiers might
- change the protein's location (localization signals)
- enable it to be readily purified (affinity tags)
- alter the protein's degradation rate (degradation tags)
- target the protein for cleavage (cleavage sites)
Protein tags may include a start codon or a stop codon, but not both, since they are intended to be assembled in frame with protein coding sequences.
