Furthermore, the phosphorylated I kappa B alpha from calyculin A -treated cells , but not that from TNF-alpha -stimulated cells , is sensitive to PP-2A in vitro, suggesting the existence of fundamental differences in the phosphorylation of I kappa B alpha induced by the two different NF-kappa B inducers .
