Post-translational-modifications (PTM), amino acid modifications of proteins after translation, are one of the posterior
processes of protein biosynthesis for many proteins, and they are critical for determining protein function such as its
activity state, localization, turnover and interactions with other biomolecules. While there have been many studies of
information extraction targeting individual PTM types, there was until recently little effort to address extraction of
multiple PTM types at once in a unified framework.
