Inhibition of cellular protein secretion by picornaviral 3A proteins.

Abstract

During poliovirus infection, anterograde traffic between the endoplasmic reticulum and the Golgi is inhibited due to the action of 3A, an 87 amino acid viral protein. The ability of poliovirus protein 3A to inhibit ER-to-Golgi traffic is not required for virus growth. Instead, we have suggested that the inhibition of host protein secretion, shown to reduce… (More)
