Abstract

The amino-terminal cytoplasmic domains of paramyxovirus fusion glycoproteins include trafficking signals that influence protein processing and cell surface expression. This study clarified that tyrosine residues at different positions in the YLMY motif in the cytoplasmic region of the F protein regulate F protein transportation, thereby affecting viral replication and pathogenicity.
