In vitro, the ICAM-1 kappa B site appeared to bind RelA and c-Rel homodimers as well as heterodimers with NF-kappa B1 , but weakly NF-kappa B1 homodimers .
 ( DNA: ICAM-1 kappa B site, None) , ( protein: RelA, None) , ( protein: NF-kappa B1 homodimers, None) , ( protein: NF-kappa B1, None) , ( protein: c-Rel homodimers, None)
