tokens: This mutant also functions in vivo as a trans-acting dominant negative regulator : the transcriptional inducibility of the HIV long terminal repeat ( which contains two potential NF-kappa B binding sites ) by phorbol ester ( PMA ) is inhibited when it is co-transfected into CD4+ T cells with the delta SP mutant .
