Abstract
Upon infection, the herpes viruses create a cellular environment suitable for survival, but innate immunity plays a vital role in cellular resistance to viral infection. The UL13 protein of herpesviruses is conserved among all herpesviruses and is a serine/threonine protein kinase, which plays a vital role in escaping innate immunity and promoting viral replication. On the one hand, it can target various immune signaling pathways in vivo, such as the cGAS-STING pathway and the NF-κB pathway. On the other hand, it phosphorylates regulatory many cellular and viral proteins for promoting the lytic cycle. This paper reviews the research progress of the conserved herpesvirus protein kinase UL13 in immune escape and viral replication to provide a basis for elucidating the pathogenic mechanism of herpesviruses, as well as providing insights into the potential means of immune escape and viral replication of other herpesviruses that have not yet resolved the function of it.

Abstract
The DNA damage response (DDR) pathway is critical for maintaining genomic integrity and sustaining organismal development. Viruses can either utilize or circumvent the DDR to facilitate their replication. Pseudorabies virus (PRV) infection was shown to induce apoptosis via stimulating DDR. However, the underlying mechanisms have not been fully explored to date. This study showed that PRV infection robustly activates the ATM and DNA-PK signaling pathways shortly after infection. However, inhibition of ATM, but not DNA-PK, could dampen PRV replication in cells. Importantly, we found that PRV-encoded serine/threonine kinase UL13 interacts with and subsequently phosphorylates H2AX. Furthermore, we found that UL13 deletion largely attenuates PRV neuroinvasiveness and virulence in vivo. In addtion, we showed that UL13 contributes to H2AX phosphorylation upon PRV infection both in vitro and in vivo, but does not affect ATM phosphorylation. Finally, we showed that knockdown of H2AX reduces PRV replication, while this reduction can be further enhanced by deletion of UL13. Taken together, we conclude that PRV-encoded kinase UL13 regulates DNA damage marker γH2AX and UL13-mediated H2AX phosphorylation plays a pivotal role in efficient PRV replication and progeny production.

Abstract
Peroxiredoxin 1 (PRDX1) is a cellular antioxidant enzyme that is crucial for diverse fundamental biological processes, such as autophagy, inflammation, and carcinogenesis. However, molecular mechanisms underpinning its diverse roles are not well understood. Here, we report that PRDX1 positively regulates interferon (IFN) induction and that pseudorabies virus (PRV) targets PRDX1 to evade IFN induction. PRV UL13 encodes a serine/threonine kinase important for PRV infection, although its biological function remains obscure. We identified PRDX1 as a UL13-interacting protein. Virological and biochemical assays demonstrate that PRDX1 promotes IFN induction by interacting with TANK-binding kinase 1 (TBK1) and IκB kinase ε (IKKε). Conversely, UL13 accelerates PRDX1 degradation via the ubiquitin-proteosome pathway in a kinase-dependent manner. In doing so, PRV inhibits IFN induction during productive infection, which requires PRDX1 expression. This study uncovers an essential role of PRDX1 in the innate immune response and reveals a new viral immune evasion strategy to counteract cellular defenses. IMPORTANCE PRV interacts with numerous cellular proteins during productive infection. Here, we demonstrated the interaction of viral protein UL13 with the antioxidant enzyme PRDX1, which functions in multiple signal transduction pathways. We found that PRDX1 participates in the type I IFN pathway by interacting with TBK1 and IKKε, thereby negatively regulating PRV propagation. However, UL13 ubiquitinates PRDX1, which routes PRDX1 into proteasomes for degradation and effectively reduces its expression. These results illuminate the fundamental role that PRDX1 plays in the IFN pathway, and they identify a potential target for the control of PRV infection.

Abstract
Pseudorabies is a highly infectious disease with severe clinical symptoms, causing acute death in infected pigs and leading to substantial economic losses among swine producers. In this study, a vaccine candidate strain in which the protein kinase UL13 gene was deleted was constructed with the CRISPR/Cas9 system based on the recombinant pseudorabies virus (PRV) ZJ01-ΔgI/gE/TK. Pigs immunized with ZJ01-ΔgI/gE/TK or ZJ01-ΔgI/gE/TK/UL13 produced high levels of anti-gB antibodies and virus-neutralizing antibodies. ZJ01-ΔgI/gE/TK/UL13 provided greater protective efficacy against challenge with PRV variant strain ZJ01 than did Bartha-K61 or ZJ01-ΔgI/gE/TK. The pigs vaccinated with ZJ01-ΔgI/gE/TK/UL13 excreted significantly less virus than those vaccinated with Bartha-K61 or ZJ01-ΔgI/gE/TK. The viral loads in the lungs of pigs treated with ZJ01-ΔgI/gE/TK/UL13 were lower than those in pigs treated with ZJ01-ΔgI/gE/TK after challenge with PRV variant strain ZJ01. These data indicated that ZJ01-ΔgI/gE/TK/UL13 had greater protective efficacy and safety than the commercial ZJ01-ΔgI/gE/TK and Bartha-K61 vaccines, and could be developed as a promising vaccine candidate for the prevention and control of this disease.

Abstract
Duck enteritis virus (DEV) multifunctional tegument protein UL13 is predicted to be a conserved herpesvirus protein kinase; however, little is known about its subcellular localization signal. In this study, through transfection of 2 predicted nuclear signals of DEV UL13 fused to enhanced green fluorescent protein, 2 bipartite nuclear localization signals (NLS) were identified. We found that ivermectin blocked the NLS-mediated nuclear import of DEV UL13, showing that the nuclear localization signal of DEV UL13 is a classical importin α- and β-dependent process. We constructed a DEV UL13 mutant strain in which the NLS of DEV UL13 was deleted to explore whether deletion of the NLS affects viral replication. Amino acids 4 to 7 and 90 to 96 were predicted to be NLSs, further proving that nuclear import occurs via a classical importin α- and β-dependent process. We also found that the NLS of pUL13 had no effect on DEV replication in cell culture. Our study enhances the understanding of DEV pUL13. Taken together, these results provide significant information regarding the biological function of pUL13 during DEV infection.

Abstract
Pseudorabies virus (PRV), a porcine alphaherpesvirus, causes neurological disorders and reproductive failure in swine. It is capable of avoiding host antiviral responses, resulting in viral latency in infected animals. The mechanisms by which many PRV proteins help the virus to evade immune surveillance are poorly understood. In this study, we found that the PRV protein kinase, UL13, inhibits the IFN-β signaling pathway by targeting interferon regulatory factor 3 (IRF3) for ubiquitination and degradation. PRV with mutant of UL13 is impaired in its ability to hinder IRF3 and interferon-β (IFN-β) activation, and has significantly less pathogenesis in mice that wild-type PRV. Our findings reveal an as yet undescribed mechanism utilized by PRV to evade host immune responses. PRV UL13 is a potential target for attenuated vaccines and antiviral drugs.

Abstract
The UL13 protein of the duck enteritis virus (DEV), predicted to encode a Ser/Thr protein kinase, belongs to the family of conserved herpesvirus protein kinases (CHPK), which plays an important role in herpesvirus proliferation. In this study, truncated UL13 was expressed as a fusion protein of approximately 44 kDa using a prokaryotic expression system, and this protein was used to generate a specific anti-UL13 antibody. This antibody detected UL13 starting at 4 h post infection in duck embryonic fibroblast cells and identified UL13 to be present in both the cytoplasm and the nucleus. UL13 RNA was found to be transcribed starting at 2 h post infection, and the synthesis of the UL13 mRNA was found to be sensitive to the protein synthesis inhibitor cycloheximide (CHX) and tolerant of the DNA polymerase inhibitor ganciclovir (GCV). Its nuclear location and status as an early gene suggested that DEV UL13 might play important roles in DEV replication, which was confirmed by comparing the proliferation of a UL13-knockout mutant virus, a revertant virus, and the parent virus in cell culture. The specific mechanisms of UL13 in viral replication need to be further studied.

Abstract
The suppressor of cytokine signaling (SOCS) family has eight members and suppresses various cytokine signaling pathways, including IFN signaling. Therefore, some viruses have evolved molecular mechanisms for inducing SOCS proteins and thus escaping host immunity. Herpes simplex virus type 1 (HSV-1) has a mechanism for escaping from type I IFN by induction of both SOCS1 and SOCS3. In this study, expression of the eight members of the SOCS family stimulated by HSV-1 infection was comparatively analyzed by qRT-PCR. It was found that SOCS1 and SOCS3 are induced by HSV-1-infection at 4 hr post infection. However, such induction was not observed in UL13 deficient virus-infected cells, suggesting that UL13 protein kinase participates in induction of both genes. The transcription factor Sp1-binding sites of SOCS3 promoter/enhancer region were identified as the regulatory elements for induction of SOCS3 in HSV-1 infected cells. Accumulation of activated Sp1 was detectable in the nuclei of HSV-1-infected cells before induction of SOCS3. Taken together, these results suggest that HSV-1 has a potent mechanism for escaping from the IFN system.
