Protein kinase C zeta isoform is critical for kappa B-dependent promoter activation by sphingomyelinase.


Recent evidence demonstrates that the protein kinase C zeta (zeta PKC) isoform is required for the activation of nuclear factor kappa B (NF-kappa B) and mitogenic signaling in Xenopus oocytes and mammalian cells. The mechanism whereby zeta PKC regulates NF-kappa B most probably involves the activation of a putative I kappa B kinase of molecular mass… (More)
