Abstract
Activation of I{kappa}B kinase subunit {gamma} (IKK{gamma}), a key regulator of the classical NF-{kappa}B pathway, by the vFLIP protein of Kaposi's sarcoma-associated herpesvirus (KSHV) and the Tax protein of human T cell lymphotropic virus type 1 (HTLV1) is essential for virus-associated cancer. We show that vFLIP and Tax activate this pathway by different interactions with IKK{gamma} and independently of the ubiquitin-mediated signaling pathways induced by cytokines. Our data provide new insights into the mechanisms by which IKK{gamma} can be activated and show that NF-{kappa}B activation by oncogenic viruses can be targeted without affecting physiologically important pathways.
