These proteases perform the posttranslational proteolytic processing of the viral polyprotein ,
Enterovirus - associated processing of cellular proteins may also contribute to pathology ,
These proteases perform the posttranslational proteolytic processing of the viral polyprotein , but they also cleave several host - cell proteins in order to promote the production of new virus particles , as well as to evade the cellular antiviral immune responses .
Enterovirus - associated processing of cellular proteins may also contribute to pathology , as elegantly demonstrated by the 2A pro -mediated cleavage of dystrophin in cardiomyocytes contributing to Coxsackievirus - induced cardiomyopathy .
