dc.description.abstract The Tax oncoprotein plays a crucial role in the proliferation and transformation of human T-cell leukemia virus type I (HTLV-I)-infected T lymphocytes through various mechanisms, including activation of the nuclear factor (NF)-κB pathway. We found that cytoplasmic ubiquitylation of Tax C-terminal lysines is critical for Tax binding to the IkappaB kinase complex and subsequent nuclear translocation of RelA. Conversely, we demonstrate that the same lysines are sumoylated in the nucleus, an event required for the formation of RelA-p300-enriched Tax nuclear bodies and full NF-κB transcriptional activation. In contrast, Tax ubiquitylation and sumoylation are dispensable for its activation of cyclic adenosine monophosphate response element binding protein (CREB)-dependent genes. Thus, ubiquitylation and sumoylation of the same residues of Tax regulate 2 essential steps controlling NF-κB activation, demonstrating how these post-translational modifications can cooperate to promote Tax-induced transformation. © 2006 by The American Society of Hematology.
