产品提供形式：

Liquid or Lyophilized powder

缓冲液：

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.

储存条件：

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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

保质期：

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℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.

货期：

3-7 business days

注意事项：

Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

功能1：

SUMO-targeted ubiquitin ligase that plays an essential role in nuclear antiviral defense evasion triggered by dsDNA viruses. Acts during the initial stages of lytic infection and the reactivation of latent viral genome. Prevents the antiviral effect of nuclear bodies by degrading host PML, SP100 and MORC3. Prevents antiviral response to viral DNA induced by IFI16 by degrading it. Additionally, inhibits host IRF3 nuclear signaling to prevent interferon production by the infected cells. Interestingly, the E3 ubiquitin ligase activity associated with the RING finger domain does not seem to be directly required to inhibit the activation of IRF3 but instead plays a critical role in modulating the cellular localization of ICP0. Upon reactivation of latent genome, suppresses the silencing of viral DNA by dissociating either HDAC1 or HDAC2 from the HDAC-RCOR1-REST-KDM1A complex localized at the ND10 structures and causes their dispersal. Two cellular histone ubiquitin ligases RNF8 and RNF168 are also targeted by ICP0 for degradation, leading to a loss of ubiquitinated forms of H2A, a relief of transcriptional repression, and the activation of latent viral genomes. Enhances the localization of host CCND3 to ND10 bodies that serve as precursors of replication compartments to enable efficient viral replication. Like many RING-finger E3 ubiquitin ligases, ICP0 can induce its own ubiquitination, an activity that promotes its instability due to its targeting to the 26S proteasome for degradation. ICP0 restricts this process by recruiting the cellular ubiquitin-specific protease USP7 that cleaves the anchored ubiquitin chains from ICP0, thereby promoting its stabilization.
