The AP-1 adaptor complex is essential for intracellular trafficking of the ORF2 capsid protein and assembly of Hepatitis E virus. Cell Mol Life Sci 2024; 81:335. [PMID: 39117755 PMCID: PMC11335258 DOI: 10.1007/s00018-024-05367-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 07/03/2024] [Accepted: 07/15/2024] [Indexed: 08/10/2024]
Abstract
Although the Hepatitis E virus (HEV) is an emerging global health burden, little is known about its interaction with the host cell. HEV genome encodes three proteins including the ORF2 capsid protein that is produced in different forms, the ORF2i protein which is the structural component of viral particles, and the ORF2g/c proteins which are massively secreted but are not associated with infectious material. We recently demonstrated that the endocytic recycling compartment (ERC) is hijacked by HEV to serve as a viral factory. However, host determinants involved in the subcellular shuttling of viral proteins to viral factories are unknown. Here, we demonstrate that the AP-1 adaptor complex plays a pivotal role in the targeting of ORF2i protein to viral factories. This complex belongs to the family of adaptor proteins that are involved in vesicular transport between the trans-Golgi network and early/recycling endosomes. An interplay between the AP-1 complex and viral protein(s) has been described for several viral lifecycles. In the present study, we demonstrated that the ORF2i protein colocalizes and interacts with the AP-1 adaptor complex in HEV-producing or infected cells. We showed that silencing or drug-inhibition of the AP-1 complex prevents ORF2i protein localization in viral factories and reduces viral production in hepatocytes. Modeling of the ORF2i/AP-1 complex also revealed that the S domain of ORF2i likely interacts with the σ1 subunit of AP-1 complex. Hence, our study identified for the first time a host factor involved in addressing HEV proteins (i.e. ORF2i protein) to viral factories.

Fos Facilitates Gallid Alpha-Herpesvirus 1 Infection by Transcriptional Control of Host Metabolic Genes and Viral Immediate Early Gene. Viruses 2021; 13:v13061110. [PMID: 34207926 PMCID: PMC8229045 DOI: 10.3390/v13061110] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 06/04/2021] [Accepted: 06/08/2021] [Indexed: 12/24/2022] Open
Abstract
Gallid alpha-herpesvirus 1, also known as avian infectious laryngotracheitis virus (ILTV), continues to cause huge economic losses to the poultry industry worldwide. Similar to that of other herpesvirus-encoded proteins, the expression of viral genes encoded by ILTV is regulated by a cascade, and the underlying regulatory mechanism remains largely unclear. The viral immediate-early (IE) gene ICP4 plays a prominent role in the initiation of the transcription of early and late genes during ILTV replication. In this study, we identified AP-1 as the key regulator of the transcription of ILTV genes by bioinformatics analysis of genome-wide transcriptome data. Subsequent functional studies of the key members of the AP-1 family revealed that Fos, but not Jun, regulates ILTV infection through AP-1 since knockdown of Fos, but not Jun, by gene silencing significantly reduced ICP4 transcription and subsequent viral genome replication and virion production. Using several approaches, we identified ICP4 as a bona fide target gene of Fos that regulated Fos and has Fos response elements within its promoter. Neither the physical binding of Jun to the promoter of ICP4 nor the transcriptional activity of Jun was observed. In addition, knockdown of Fos reduced the transcription of MDH1 and ATP5A1, genes encoding two host rate-limiting enzymes essential for the production of the TCA intermediates OAA and ATP. The biological significance of the transcriptional regulation of MDH1 and ATP5A1 by Fos in ILTV infection was supported by the fact that anaplerosis of OAA and ATP rescued both ICP4 transcription and virion production in infected cells under when Fos was silenced. Our study identified the transcription factor Fos as a key regulator of ILTV infection through its transcription factor function on both the virus and host sides, improving the current understanding of both avian herpesvirus–host interactions and the roles of AP-1 in viral infection.

Abstract
Numerous viruses hijack cellular protein trafficking pathways to mediate cell entry or to rearrange membrane structures thereby promoting viral replication and antagonizing the immune response. Adaptor protein complexes (AP), which mediate protein sorting in endocytic and secretory transport pathways, are one of the conserved viral targets with many viruses possessing AP-interacting motifs. We present here different mechanisms of viral interference with AP complexes and the functional consequences that allow for efficient viral propagation and evasion of host immune defense. The ubiquity of this phenomenon is evidenced by the fact that there are representatives for AP interference in all major viral families, covered in this review. The best described examples are interactions of human immunodeficiency virus and human herpesviruses with AP complexes. Several other viruses, like Ebola, Nipah, and SARS-CoV-2, are pointed out as high priority disease-causative agents supporting the need for deeper understanding of virus-AP interplay which can be exploited in the design of novel antiviral therapies.

Abstract
The polymerase complex of Ebola virus (EBOV) is the functional unit for transcription and replication of viral genome. Nucleoprotein (NP) is a multifunctional protein with high RNA binding affinity and recruits other viral proteins to form functional polymerase complex. In our study, we investigated host proteins associated with EBOV polymerase complex using NP as bait in a transcription and replication competent minigenome system by mass spectrometry analysis and identified SET and MYND domain-containing protein 3 (SMYD3) as a novel host protein which was required for the replication of EBOV. SMYD3 specifically interacted with NP and was recruited to EBOV inclusion bodies through NP. The depletion of SMYD3 dramatically suppressed EBOV mRNA production. A mimic of non-phosphorylated VP30, which is a transcription activator, could partially rescue the viral mRNA production downregulated by the depletion of SMYD3. In addition, SMYD3 promoted NP-VP30 interaction in a dose-dependent manner. These results revealed that SMYD3 was a novel host factor recruited by NP to supporting EBOV mRNA transcription through increasing the binding of VP30 to NP. Thus, our study provided a new understanding of mechanism underlying the transcription of EBOV genome, and a novel anti-EBOV drug design strategy by targeting SMYD3.

Suppression of µ1 subunit of the adaptor protein complex 2 reduces dengue virus release. Virus Genes 2019; 56:27-36.

Abstract
Dengue virus (DENV) requires clathrin-mediated endocytosis for its entry into the cells where the adaptor protein complex (AP) is vital for the clathrin-coated vesicle formation. The role of AP-2 was previously examined in the early stages of DENV infection; however, the role of AP-2 in the late stage of DENV infection was not determined. The µ1 subunit of AP-2 (AP2M1) is one of the most important cytoplasmic carrier domains in clathrin-mediated endocytosis and the phosphorylation of this subunit by the kinase enzyme, AP-2 associated protein kinase 1 (AAK1), stimulates clathrin and supports the cell surface receptor incorporation. In the present study, we primarily aimed to investigate the role of AP2M1 by gene silencing approach as well as using naked DENV RNA transfection into AP2M1 knockdown cells. Secondarily, an inhibitor of AAK1, sunitinib was used to investigate whether AAK1 could influence the virus production in DENV-infected Huh7 cells. The knockdown of AP2M1 in the DENV-infected Huh7 cells displayed a reduction in the viral titer at 24 h post-infection. Furthermore, experiments were conducted to bypass the DENV internalization using a naked DENV RNA transfection into the AP2M1 knockdown cells. Higher intracellular DENV RNA, DENV E protein, and intracellular virion were observed, whereas the extracellular virion production was comparably less than that of control. Treatment with sunitinib in DENV-infected Huh7 cells was able to reduce extracellular virion production and was consistent with all four serotypes of DENV. Therefore, our findings demonstrate the role of AP2M1 in the exocytosis step of DENV replication leading to infectious DENV production and the efficacy of sunitinib in suppressing virus production during the infection with different serotypes of DENV.

Abstract
Dengue hemorrhagic fever is a life-threatening disease caused by the dengue virus (DENV). After DENV enters into host cells, it replicates to generate viral particles to infect other cells. DENV exploits components of the cellular trafficking pathway to achieve effective virion production. Understanding of the proteins required for this trafficking process is essential for revealing the pathogenesis of DENV infection. Coat protein complex and soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs), two host protein families in the cellular trafficking pathway, were investigated to elucidate their respective roles during DENV infection. Coat proteins (COPI and COPII) and SNAREs (STX 5 and NSF) were knocked down in a DENV-infected Huh7 cells by RNA interference. Depletion of COPI and COPII, but not of STX5 and NSF, decreased DENV production in DENV-infected Huh7 cells. DENV proteins, including DENV C, prM, E, and NS1, were significantly reduced in COPI-silenced DENV-infected Huh7 cells, when compared to those of control cells. COPI also facilitated DENV production in an endothelial cell line and in all DENV serotypes, indicating the importance of coat protein complex in facilitating DENV infection.
