A predominance of p50 NF-kappa B moieties and possibly p50 homodimers or closely related species, rather than the p50-p56 heterodimer of NF-kappa B that is the predominant NF-kappa B species in most T lymphocytic and monocytic cells , is demonstrated in the nuclei of U1 cells .
 ( protein: p50 homodimers, None) , ( protein: NF-kappa B moieties, None) , ( protein: p50-p56 heterodimer, None) , ( protein: NF-kappa B, None) , ( protein: p50 NF-kappa B moieties, None) , ( protein: NF-kappa B, None) , ( cell line: U1 cells, None)
