By using recombinant proteins , we confirmed that AP-1 , NF-ATp , and a higher order NF-ATp / AP-1 complex could all form with the hCLEO element , and we have also defined the sequence requirements for binding of each of these complexes.
 ( DNA: hCLEO, None) , ( protein: recombinant proteins, None) , ( protein: AP-1, None) , ( protein: NF-ATp, None) , ( protein: AP-1, None) , ( protein: NF-ATp / AP-1 complex, None) , ( DNA: hCLEO element, None) , ( protein: NF-ATp, None)
