A mutant Tax protein deficient in transactivation of genes by the nuclear factor (NF)-kappaB pathway was unable to induce transcriptional activity of IL-1alpha promoter -CAT constructs , but was rescued by exogenous provision of p65/p50 NF-kappaB .
 ( protein: NF-kappaB, None) , ( DNA: IL-1alpha promoter, None) , ( DNA: IL-1alpha promoter -CAT constructs, None) , ( protein: IL-1alpha, None) , ( protein: p65/p50, None) , ( protein: nuclear factor (NF)-kappaB, None) , ( protein: Tax protein, None)
