Glycosylation is an important posttranslational modification that influences protein folding, antigenicity, and biological activity, and the F and HN proteins of HPIVs are closely related to viral infection (Yao et al., 1997; Komada et al., 2000; Chu et al., 2013; Steentoft et al., 2013). This evidence concerns the gene MT-RNR2 and viral infectious disease.
