FUNCTION: Transcriptional activator that governs the viral transcription from the 5'LTR via the recruitment of dimers of host phosphorylated CREB1. Together they bind cAMP response elements within the viral promoter and mediate high-level viral transcription (PubMed:8970957, PubMed:22789739). Increases host CREB1 O-GlcNAcylation to further increase 5'LTR transactivation (PubMed:28742148). Modulates also the expression of cellular genes leading to the deregulation of T-cell proliferation, perturbing the integrity of cell cycle checkpoints, the DNA damage response and apopototic pathways. Acts as an ubiquitin E3 ligase and stimulates host IKK complex by catalyzing the assembly of free mixed-linkage polyubiquitin chains, resulting in constitutive activation of the transcription factor NF-kappa-B (PubMed:28103322, PubMed:27082114). Inhibits the host nonsense-mediated mRNA decay (NMD), a cellular process that can actively degrade mRNAs by interacting with host UPF1 (PubMed:27082114). {ECO:0000269|PubMed:12052856, ECO:0000269|PubMed:15466468, ECO:0000269|PubMed:16809310, ECO:0000269|PubMed:22789739, ECO:0000269|PubMed:27082114, ECO:0000269|PubMed:2768259, ECO:0000269|PubMed:28103322, ECO:0000269|PubMed:28742148, ECO:0000269|PubMed:29382845, ECO:0000269|PubMed:2990037, ECO:0000269|PubMed:8970957}.
Subellular location
SUBCELLULAR LOCATION: Host nucleus {ECO:0000269|PubMed:15269214, ECO:0000269|PubMed:22789739}. Host cytoplasm {ECO:0000269|PubMed:15269214, ECO:0000269|PubMed:22789739, ECO:0000269|PubMed:29665857}. Note=Shuttles from the host nucleus to the cytoplasm. Found predominantly in the nucleus, where it is equally distributed between the nucleoplasm and the nuclear matrix.
SUBUNIT: Homodimer. Interacts with host CREB1 (PubMed:8970957). Interacts with host DLG1, IKBKG, KDM4A, MAGII3 and TAX1BP1. Recruits the coactivators CREBBP, EP300 and PCAF (PubMed:10766811). Interaction with human CARM1 enhances Tax transactivation and promotes methylation of histone H3 (PubMed:17005681). Interacts with host SUV39H1 protein, leading to abrogate Tax transactivation of HTLV-1 LTR (PubMed:16409643). Interaction with human CREB coactivators, CRTC1/TORC1, CRTC2/TORC2 and CRTC3/TORC3 enhances Tax transactivation (PubMed:15466468, PubMed:16809310). Interacts with host UPF1; this interaction inhibits the host nonsense-mediated mRNA decay (NMD). Interacts (via N-terminus) with host PLSCR1; this interaction negatively regulates Tax transactivation activity by altering its subcellular distribution and homodimerization (PubMed:22789739). {ECO:0000269|PubMed:10557085, ECO:0000269|PubMed:10766811, ECO:0000269|PubMed:11064457, ECO:0000269|PubMed:11463834, ECO:0000269|PubMed:1386673, ECO:0000269|PubMed:14530271, ECO:0000269|PubMed:15003862, ECO:0000269|PubMed:15466468, ECO:0000269|PubMed:15927959, ECO:0000269|PubMed:16409643, ECO:0000269|PubMed:16809310, ECO:0000269|PubMed:17005681, ECO:0000269|PubMed:22789739, ECO:0000269|PubMed:29382845, ECO:0000269|PubMed:8970957, ECO:0000269|PubMed:9016568, ECO:0000269|PubMed:9528808}.
Post-translational modification
PTM: Phosphorylation at Thr-48 results in the loss of NF-kappa-B activation function. Phosphorylation at Thr-215 results in loss of CREB and NF-B responsive promoters activation. Phosphorylation at Thr-184 and Ser-336 have no effect on these Tax functions. Phosphorylation of either Ser-300 or Ser-301 is necessary for localization to nuclear bodies. Thr-48, Thr-184, Thr-215 and Ser-336 are highly phosphorylated, whereas Ser-300 or Ser-301 are only rarely phosphorylated. {ECO:0000269|PubMed:16923801, ECO:0000269|PubMed:9847380}.; PTM: Modified by host ubiquitin related modifier 1/URM1, resulting in a redistribution of Tax to the cytoplasm. {ECO:0000269|PubMed:29665857}.
