CC -!- FUNCTION: Accepts ubiquitin from the E1 complex and catalyzes its
CC covalent attachment to other proteins (By similarity). Performs the
CC second step in the ubiquitination reaction that targets specifically a
CC protein for degradation via the proteasome (By similarity). By
CC controlling the ubiquitination status of specific host proteins, the
CC virus may target them to degradation and thereby optimize the viral
CC replication (By similarity). May be implicated in the shutoff of
CC protein synthesis through its interactions with components of the host
CC translation machinery (By similarity). Blocks p65 nuclear translocation
CC upon cytokine stimulation, thereby impairing NF-kappa-B signaling (By
CC similarity). Inhibits type I IFN production and 'Lys-63'-linked
CC polyubiquitination of host TBK1 through binding to host RNF138. This
CC binding enhances the interaction between RNF138 and RNF128 and promotes
CC RNF138-mediated degradation of RNF128. Also inhibits the activation of
CC AP-1 transcription factor (By similarity). Monoubiquitinates the viral
CC protein P15/PIG1 in vitro (By similarity).
