We show here that in addition to the strong N-terminal trans-activation domain , TAD-A , which is common to all three NF-ATc isoforms , NF-ATc /C contains a second trans-activation domain , TAD-B , in its C-terminal peptide .
 ( protein: NF-ATc, None) , ( protein: NF-ATc isoforms, None) , ( protein: TAD-B, None) , ( protein: TAD-A, None) , ( protein: NF-ATc, None) , ( protein: NF-ATc /C, None) , ( protein: trans-activation domain, None) , ( protein: strong N-terminal trans-activation domain, None)
