Using electrophoretic mobility shift assays , we showed binding of purified human NF-kappa B and of the NF-kappa B activated in Jurkat T cells to an oligonucleotide comprising the GM-CSF promoter element responsible for mediating responsiveness to T-cell-activating signals and tax1 .
 protein: NF-kappa B; cell type: T cells; protein: GM-CSF; cell line: Jurkat T cells; protein: human NF-kappa B; protein: NF-kappa B; protein: tax1; DNA: GM-CSF promoter element
