Subsequent studies have revealed that (i) cytoplasmic RelA is stably associated not only with I kappa B alpha but also with other ankyrin motif-rich proteins including the products of the NF-kappa B2 (p100) and NF-kappa B1 (p105) genes ; (ii) in contrast to RelA -I kappa B alpha , RelA -p100 cytoplasmic complexes are not dissociated following tumor necrosis factor alpha activation; (iii) p100 functions as a potent inhibitor of RelA -mediated transcription in vivo; (iv) the interaction of RelA and p100 involves the conserved Rel homology domain of both proteins but not the nuclear localization signal of RelA , which is required for I kappa B alpha binding ; (v) p100 inhibition of RelA function requires the C-terminal ankyrin motif domain , which mediates cytoplasmic retention of RelA ; and (vi) as observed with I kappa B alpha , nuclear RelA stimulates p100 mRNA and protein expression .
