The transcription factors active at the IL-2 promoter were differentially influenced: upon down-modulation of okadaic acid -sensitive phosphatases , transactivation by octamer, NF-kappa B , and NF of activated T cells proteins was abrogated, while transactivation by AP-1 proteins was even enhanced.
