ResumoABSTRACT The assembly and egress of herpesviruses are complex processes that require the budding of viral nucleocapsids into the lumen of cytoplasmic compartments to form mature infectious virus. This envelopment stage shares many characteristics with the formation of luminal vesicles in multivesicular endosomes. Through expression of dominant-negative Vps4, an enzyme that is essential for the formation of luminal vesicles in multivesicular endosomes, we now show that Vps4 function is required for the cytoplasmic envelopment of herpes simplex virus type 1. This is the first example of a large enveloped DNA virus engaging the multivesicular endosome sorting machinery to enable infectious virus production.
