We report that a constitutively active form of calcineurin partially substitutes for the Ca2+ co-stimulus required to activate the IL-2 promoter elements IL-2A (which binds the factors OAP and Oct-1 ) and IL-2E (which binds NF-AT ), and completely substitutes for the Ca2+ co-stimulus required to stimulate an NF-kappa B -dependent element.
 NF-kappa B, IL-2 promoter elements, IL-2 promoter, NF-AT, IL-2A, IL-2E, Oct-1, calcineurin, OAP
