dc.description.abstract | Many viral transcriptional activators have been shown to activate genes of heterologous systems. To assess the ability of the herpes simplex virus ICP4 trans-activating protein to complement an adenovirus mutant lacking its own trans-activator, the E1a protein, I constructed an adenovirus type 5 vector containing a temperature sensitive ICP4 gene, under control of its own promoter, within the E1 region of the genome. The recombinant virus expresses ICP4 in human cells which are permissive (293) or nonpermissive (KB and R970-5) for E1a⁻ viral replication, and at levels which approximate those obtained in herpes simplex infection. The adenovirus encoded protein is functional in that it complements an ICP4 deletion mutant of herpes simplex virus, however it is incapable of complementing adenovirus E1a⁻ mutants for viral growth or DNA replication. At the level of activation of gene expression, ICP4 stimulates the expression of the adenovirus E2a gene but not that of other early genes. My results indicate that ICP4 does not possess all of the functions of the E1a proteins and, furthermore, that adenovirus early genes differ in their susceptibility to heterologous trans-activators. | en_US |
