Plays a major role to prevent cellular inhibition of viral genome replication by nuclear bodies. Assembles an SCF-like E3 ubiquitin ligase complex based on the cellular proteins ELOB, ELOC, CUL5 and RBX1, in cooperation with viral E1B-55K. This viral RING-type ligase ubiquitinates cellular substrates prior to proteasomal degradation: p53/TP53, LIG4, MRE11-RAD50-NBS1 (MRN) complex, ITGA3, DAXX and BLM.

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 adenovirus E1b55K/E4orf6 complex induces degradation of the Bloom helicase during infection." Orazio N.I., Naeger C.M., Karlseder J., Weitzman M.D. J. Virol. 85:1887-1892 (2011)

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.
