“…At high MOIs, viral replication appears to circumvent the requirements of ICP0, because under these conditions, replication is not dependent on ICP0 (67). A previous study reported that HSV-1 ICP0 interacts specifically with transforming growth factor-activated protein kinase 1 and stimulates c-Jun N-terminal kinase activity but has no effect on ERK activity (19). Our results are consistent with this report; tankyrase 1 was not phosphorylated in ICP0-overexpressing cells.…”

Tankyrase 1 is a poly(ADP-ribose) polymerase (PARP) which localizes to multiple subcellular sites, including telomeres and mitotic centrosomes. Poly(ADP-ribosyl)ation of the nuclear mitotic apparatus (NuMA) protein by tankyrase 1 during mitosis is essential for sister telomere resolution and mitotic spindle pole formation. In interphase cells, tankyrase 1 resides in the cytoplasm, and its role therein is not well understood. In this study, we found that herpes simplex virus (HSV) infection induced extensive modification of tankyrase 1 but not tankyrase 2. This modification was dependent on extracellular signal-regulated kinase (ERK) activity triggered by HSV infection. Following HSV-1 infection, tankyrase 1 was recruited to the nucleus. In the early phase of infection, tankyrase 1 colocalized with ICP0 and thereafter localized within the HSV replication compartment, which was blocked in cells infected with the HSV-1 ICP0-null mutant R7910. In the absence of infection, ICP0 interacted with tankyrase 1 and efficiently promoted its nuclear localization. HSV did not replicate efficiently in cells depleted of both tankyrases 1 and 2. Moreover, XAV939, an inhibitor of tankyrase PARP activity, decreased viral titers to 2 to 5% of control values. We concluded that HSV targets tankyrase 1 in an ICP0-and ERK-dependent manner to facilitate its replication. Herpes simplex virus types 1 and 2 (HSV-1 and HSV-2), members of the Herpesviridae family (17), possess large DNA genomes, share virion structures and replication mechanisms, and establish lifelong latency in host cells. The HSV genome comprises a 152-kb double-stranded DNA molecule that encodes approximately 80 gene products expressed in a temporally regulated cascade (6, 68). HSV genes are classified into three groups: immediate-early, early, and late genes. Immediate-early genes are expressed first upon infection and encode several transactivators, which in turn initiate transcription of the other early and some late genes; the latter are called leaky late or ␥1 genes (12,20,48,73). Early gene products include viral DNA replication factors that initiate viral DNA synthesis, which in turn stimulate expression of ␥1 and true late (␥2) genes, encoding mainly virion structural proteins.The immediate-early viral proteins ICP4, ICP27, ICP0, and ICP22 allow the virus to create an environment conducive to infection and counteract the intrinsic ability of cells to inhibit viral infection (29,34,55,59). ICP4 and ICP27 play essential roles in stimulating robust viral gene expression (34). The immediateearly protein ICP0 activates viral and cellular gene expression and functions as an E3 ubiquitin ligase that degrades several cellular proteins (29). ICP0 targets the promyelocytic leukemia protein (PML), a major component of nuclear foci called ND10 bodies that repress viral gene expression. ICP0 interferes with several intrinsic host defense mechanisms, including the host interferon responses (29), thereby playing a major role in establishing permissive conditions for viral infec...

“…Under these circumstances, JNK activation may influence important cellular consequences, such as alterations in gene expression (1,53,59,162,167,176,199,294,325,326,346), cell death (58,89,137,139,169,193,243,293), viral replication, persistent infection or progeny release (215,224,251,260), or altered cellular proliferation (178). The exact mechanism of JNK activation under each of these circumstances remains to be elucidated fully, although there may be involvement of Toll-like receptors, direct pathway modulation through interaction with upstream protein regulators, or the activation following an ER stress response (79,87,110,124,143,191,253,261,279,294,312).…”

SUMMARY The c-Jun N-terminal kinases (JNKs) are members of a larger group of serine/threonine (Ser/Thr) protein kinases from the mitogen-activated protein kinase family. JNKs were originally identified as stress-activated protein kinases in the livers of cycloheximide-challenged rats. Their subsequent purification, cloning, and naming as JNKs have emphasized their ability to phosphorylate and activate the transcription factor c-Jun. Studies of c-Jun and related transcription factor substrates have provided clues about both the preferred substrate phosphorylation sequences and additional docking domains recognized by JNK. There are now more than 50 proteins shown to be substrates for JNK. These include a range of nuclear substrates, including transcription factors and nuclear hormone receptors, heterogeneous nuclear ribonucleoprotein K, and the Pol I-specific transcription factor TIF-IA, which regulates ribosome synthesis. Many nonnuclear substrates have also been characterized, and these are involved in protein degradation (e.g., the E3 ligase Itch), signal transduction (e.g., adaptor and scaffold proteins and protein kinases), apoptotic cell death (e.g., mitochondrial Bcl2 family members), and cell movement (e.g., paxillin, DCX, microtubule-associated proteins, the stathmin family member SCG10, and the intermediate filament protein keratin 8). The range of JNK actions in the cell is therefore likely to be complex. Further characterization of the substrates of JNK should provide clearer explanations of the intracellular actions of the JNKs and may allow new avenues for targeting the JNK pathways with therapeutic agents downstream of JNK itself.

The TAK1-JNK cascade is required for IRF3 function in the innate immune response

Interferon regulatory factor (IRF)3 is critical for the transcriptional induction of chemokines and cytokines during viral or bacterial invasion. The kinases Tank binding kinase (TBK)1 and Ikappa B kinase (IKK)ε can phosphorylate the C-terminal part of IRF3 and play important roles in IRF3 activation. In this study, we show that another kinase, c-Jun-NH 2 -terminal kinase (JNK), phosphorylates IRF3 on its N-terminal serine 173 residue, and TAK1 can stimulate IRF3 phosphorylation via JNK. JNK specific inhibitor SP600125 inhibits the N-terminal phosphorylation without affecting the C-terminal phosphorylation. In addition, IRF3-mediated gene expressions on lipopolysaccharide (LPS) or polyinosinic-cytidylic acid (polyI:C) treatment are severely impaired by SP600125, as well as for reporter gene assay of IRF3 activation. Knockdown of TAK1 further confirmed these observations. Interestingly, constitutive active IRF3(5D) can be inhibited by SP600125; JNK1 can synergize the action of IRF3(5D), but not the S173A-IRF3(5D) mutant. More importantly, polyI:C failed to induce the phosphorylation of mutant S173A and SP600125 dramatically abrogated IRF3 phosphorylation and dimerization that was stimulated by polyI:C. Thus, this study demonstrates that the TAK1-JNK cascade is required for IRF3 function, in addition to TBK1/IKKε, uncovering a new mechanism for mitogen-activated protein (MAP) kinase to regulate the innate immunity.
