We have recently characterized that influenza A virus blocks autophagosome degradation via its matrix protein 2. Matrix protein 2 seems to achieve this macroautophagy inhibition not by its well-characterized proton channel function, but possibly due to its binding to Atg6/Beclin 1, thereby enhancing the death of its host cell. Here we discuss several viruses that now have been described to compromise macroautophagy via binding to Atg6/Beclin 1 with different outcomes for their replication, and how interaction with one and the same protein could inhibit autophagosome generation or degradation.
