We further demonstrate that Tax induction of nuclear c-Rel expression is activated by the RelA ( p65 ) subunit of NF-kappa B , which activates transcription of the c-rel gene through an intrinsic kappa B enhancer element .
 ( protein: RelA, None) , ( protein: p65, None) , ( DNA: kappa B enhancer element, None) , ( DNA: c-rel gene, None) , ( protein: NF-kappa B, None) , ( protein: c-Rel, None) , ( protein: Tax, None)
