Sialylation and Glycosylation Modifications in NGPs: A Comprehensive Analysis

As shown in Fig. 5, over 90% of NGPs exhibit sialylation type modifications in various GO terms, including 'blood particles', 'platelet degranulation', 'heparin binding', 'serine type endopeptidase inhibitor activity', 'antigen binding', 'endopeptidase inhibitor activity', and 'protease binding'. Specifically, more than 90% of NGPs involved in 'heparin binding' and 'antigen binding' also undergo fucosylation. Additionally, approximately 90% of NGPs in the 'viral receptor activity' term have oligomannose type glycans modified.
