We found, however, that PI 3-kinase profoundly influenced the transactivation capacity of ' nuclear factor of activated T cells ' ( NF-AT ) elicited by the TCR : expression of an activated form of PI 3-kinase inhibited TCR -mediated NF-AT responses , whereas expression of a dominant negative mutant of PI 3-kinase potently enhanced TCR -controlled NF-AT induction .
