KSHV 潜伏期可以被设想为促进病毒基因表达和裂解复制的因素与促进基因沉默和建立或维持潜伏期的因素之间平衡的结果。大量工作集中在与 KSHV 潜伏或裂解状态相关的关键病毒调节蛋白的活性上。此外,最近的研究也开始记录 KSHV 病毒基因组在潜伏和重新激活期间表观遗传景观进化的重要性。然而,KSHV 分子病毒学的一个领域在很大程度上仍未得到解答,即翻译后修饰对潜伏和重新激活期间起作用的病毒因子的活性的精确作用。在这篇综述中,我们将总结与三种病毒因子相关的翻译后修饰,这些因子的活性有助于病毒状态。讨论的病毒蛋白是 KSHV 编码的两种主要转录因子,K-Rta(KSHV 复制和转录激活因子)和 K-bZIP(KSHV 碱性亮氨酸拉链)以及病毒潜伏期相关核抗原 (LANA)。将特别强调 sumoylation 途径在 KSHV 生命周期调节中的作用。还将展示新发现的 LANA 和 K-Rta 的小泛素样修饰剂 (SUMO) 相关特性,即 LANA 组蛋白靶向 SUMO E3 连接酶活性和 K-Rta SUMO 靶向泛素连接酶功能。
KSHV latency can be envisioned as an outcome that is balanced between factors that promote viral gene expression and lytic replication against those that facilitate gene silencing and establish or maintain latency. A large body of work has focused on the activities of the key viral regulatory proteins involved in KSHV latent or lytic states. Moreover, recent studies have also begun to document the importance of epigenetic landscape evolution of the KSHV viral genome during latency and reactivation. However, one area of KSHV molecular virology that remains largely unanswered is the precise role of post-translational modifications on the activities of viral factors that function during latency and reactivation. In this review, we will summarize the post-translational modifications associated with three viral factors whose activities contribute to the viral state. The viral proteins discussed are the two major KSHV encoded transcription factors, K-Rta (KSHV replication and transcriptional activator) and K-bZIP (KSHV basic leucine zipper) and the viral latency-associated nuclear antigen (LANA). A special emphasis will be placed on the role of the sumoylation pathway in the modulation of the KSHV lifecycle. Newly uncovered small ubiquitin-like modifier (SUMO)-associated properties of LANA and K-Rta will also be presented, namely LANA histone targeting SUMO E3 ligase activity and K-Rta SUMO-targeted ubiquitin ligase function.
