The herpes simplex virus type 1 reactivation function lies outside the latency-associated transcript open reading frame ORF-2

Abstract

The latency-associated transcription unit has been shown to be important for in vivo reactivation of herpes simplex virus from the latent state. A recombinant virus was constructed to alter the largest open reading frame in this region. This virus had a wild-type reactivation phenotype, suggesting that herpes simplex virus does not require a protein function from this reading frame for efficient reactivation from latency.
