We describe here a heterodimeric binding complex of NF-kappaB subunits ( c-Rel and p65 ) which is identical to the one obtained using the HIV-LTR-kappaB site as recognition sequence and different from the one ( c-Rel and p50 ) observed with nuclear extracts from Mo T-lymphoid HTLV-II infected cells .
 p50, c-Rel, NF-kappaB subunits, p65, Mo T-lymphoid HTLV-II infected cells, heterodimeric binding complex, c-Rel, NF-kappaB, HIV-LTR-kappaB site
