Abstract
ABSTRACT The mature virion of the alphaherpesvirus pseudorabies virus (PrV) contains a minimum of 31 structural proteins which are recruited into the virus particle by a network of protein-protein interactions which is only incompletely understood. We show here that deletion of the tegument protein pUL21 resulted in a drastic decrease in the incorporation of the pUL46, pUL49, and pUS3 tegument components into mature virions. Moreover, the attenuated PrV strain Bartha (PrV-Ba), which, among other defects, carries mutations in pUL21, also fails to package pUL46, pUL49, and pUS3 efficiently. By the reconstitution of wild-type pUL21 expression to PrV-Ba and the transfer of mutated PrV-Ba pUL21 into wild-type PrV, we demonstrate that this phenotype is due to the mutated pUL21.
