We constructed a recombinant virus containing a promoter mutation altering the immediate-early expression of the HSV-1 ICP27 transcript, ICP27ΔSma, which contains a deletion of the “TATGARAT” and surrounding sequences, but retains the rest of the ICP27 promoter. This mutant does not exhibit immediate-early expression of ICP27 using criteria of expression in the absence of de novo protein synthesis and earliest expression in the kinetic cascade. While transcript abundance at 1h after infection at 0.1 PFU/cell in mouse embryo fibroblasts was significantly altered compared to infections withwt-rescues, by 4h after infection these differences were diminished or absent. Consistent with this observation, levels of some critical proteins were reduced in the mutant as compared to rescue infections at the earliest times tested, but were equivalent by 8–12h pi. Further, both single and multi-step virus replication was equivalent with both mutants and rescues. Thus, altering the immediate early kinetics of ICP27 leads to a sub-optimal quantitative lag-phase in gene expression but without consequence to replication fitnessin vitro.Infectionsin vivoalso revealed the ability of mutant and rescue virus to invade the CNS of mice following footpad injections was equivalent. The nature of the role of immediate-early ICP27 expression is discussed in light of these observations.
