单纯疱疹病毒 1 (HSV-1) 编码的立即早期蛋白 ICP0 被认为可以激活转录,从而激活有效感染。 ICP0 介导的反式激活的精确机制正在深入研究中。在这里,我们证明 ICP0 可以特异性地强烈激活 AP-1 反应基因。这种激活被 c-Jun (S73A)、c-Jun (S63/73A)、TAK1 (K63W) 抑制,但不被 p38 (AF)、ERK1 (K71R)、ERK2 (K52R) 和 TRAF6 (C85A/H87A) 抑制。我们使用各自的抑制剂 PD98059、SP600125 和 SB202190 进一步研究了 ERK、JNK 和 p38 MAPK 通路的相关性。仅 SP600125 显着减弱 ICP0 引起的 AP-1 反应基因激活。与这些一致的是,JNK 响应 ICP0 显着激活,并且这种 JNK 激活被 TAK1 (K63W) 显着减弱。事实证明,ICP0 与 TAK1 特异性相互作用并刺激其激酶活性。这些发现揭示了 ICP0 探索的调节基因表达的新分子机制。
The immediate early protein ICP0 encoded by herpes simplex virus 1 (HSV-1) is believed to activate transcription and consequently productive infection. The precise mechanisms of ICP0-mediated transactivation are under intensive study. Here, we demonstrate that ICP0 can strongly activate AP-1 responsive genes specifically. This activation is inhibited by c-Jun (S73A), c-Jun (S63/73A), TAK1 (K63W), but not by p38 (AF), ERK1 (K71R), ERK2 (K52R) and TRAF6 (C85A/H87A). We further investigate the relevancy of ERK, JNK and p38 MAPK pathways using their respective inhibitors PD98059, SP600125 and SB202190. Only SP600125 significantly attenuates the AP-1 responsive gene activation by ICP0. Consistent with these, the JNK is remarkably activated in response to ICP0, and this JNK activation is shown to be significantly attenuated by TAK1 (K63W). It turns out that ICP0 interacts specifically with TAK1 and stimulates its kinase activity. These findings reveal a new molecular mechanism ICP0 explores to regulate gene expression.
