  • Glycoproteomic measurement of site-specific polysialylation

    • Authors : Pelingon, Ruby; Pegg, Cassandra L; Zacchi, Lucia F (2020)

  • Polysialylation is the enzymatic addition of a highly negatively charged sialic acid polymer to the non-reducing termini of glycans. Polysialylation plays an important role in development, and is involved in neurological diseases, neural tissue regeneration, and cancer. Polysialic acid (PSA) is also a biodegradable and non-immunogenic conjugate to therapeutic drugs to improve their pharmacokinetics. PSA chains vary in length, composition, and linkages, while the specif...

  • Identification of novel glycosylation events on human serum-derived Factor IX

    • Authors : Pegg, Cassandra L; Zacchi, Lucia F; Recinos, Dinora Roche (2020)

  • Human Factor IX is a highly post-translationally modified protein that is an important clotting factor in the blood coagulation cascade. Functional deficiencies in Factor IX result in the bleeding disorder haemophilia B, which is treated with plasma-derived or recombinant Factor IX concentrates. Here, we investigated the post-translational modifications of human serum-derived Factor IX and report previously undescribed O-linked monosaccharide compositions at serine 141 and&...
