Enhances viral infectivity and persistence, and facilitates proliferation of HTLV-1-infected lymphocytes. Mechanistically, inhibits Tax-mediated viral replication and NF-kappa-B activation. Plays a role in allowing infected T-cells to escape the cytotoxic T-lymphocyte response by maintaining low levels of viral protein production. Inhibits also host EP300 histone acetyltransferase (HAT) activity, reducing levels of acetylated histone H3 at 'Lys-18' (H3K18ac) in infected cells. Contributes to the accumulation of chromosomal abnormalities by inhibiting double-stranded DNA breaks (DSB) repair through the NHEJ pathway. Participates in the modulation of host immune response at multiple levels contributing to abnormal interferon signaling and viral pathogenesis.

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
