Here we report that induction of the productive virus cycle has no appreciable effects on the global levels of protein ubiquitination but is accompanied by a BPLF1-dependent decrease of cullin neddylation and stabilization of nuclear CRL substrates. The Akata-Bx1 cell line was used to study the contribution of the Ub-and NEDD8-specific deconjugase activities of the EBV large tegument protein BPLF1 to the productive virus cycle. In order to assess whether this regulatory interaction may operate during virus replication, the productive cycle was induced in Akata-Bx1 cells transiently transfected with plasmids expressing Myc-tagged CAND1 or the CAND1 Nterminus that compete for BPLF1 binding to cullins, or, as controls, the CAND1 C-terminus that binds to the opposite end of the cullin scaffold, and the empty vector ( Figure 5A ). ./cache/cord-281404-5a8au32c.txt ./txt/cord-281404-5a8au32c.txt
