A small open reading frame in pseudorabies virus and implications for evolutionary relationships between herpesviruses

Virology. 1987 Jul;159(1):193-5. doi: 10.1016/0042-6822(87)90368-0.


An open reading frame coding for an 11-kDa protein was located downstream from the gI gene of pseudorabies virus (PRV). This open reading frame is homologous to an open reading frame (US9) in an analogous position in herpes simplex virus and to an open reading frame (US1) in a different position in varicella zoster virus. The open reading frame encoding the 11-kDa protein is in a region known to be deleted in live attenuated vaccine strains of PRV.
