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)
