A Review of the Role of Shuttling Proteins in Herpesvirus Replication and Pathogenesis

Herpesviruses are complex DNA viruses that rely on host-cell machinery for replication and pathogenesis. One critical aspect of their lifecycle involves the transport of viral and host proteins between the nucleus and cytoplasm. This review aims to explore the role of shuttling proteins in herpesvirus infection, focusing on their transport mechanisms, interaction with nuclear transport receptors, and contribution to viral replication and immune evasion. the viral lifecycle is significantly impacted by the transportation of different proteins between the cytoplasm and nucleus throughout viral infection. Shuttling proteins usually consist of nuclear localization signals as well as nuclear export signals for the purpose of mediating proper positioning for themselves and other proteins. They are crucial components in nucleocytoplasmic information transmission inside the cells. The nuclear pore complex on nuclear envelope facilitates the nucleocytoplasmic transport mechanism, which is mediated by certain protein carriers. Ongoing research has progressively clarified which herpesvirus proteins function via nucleocytoplasmic shuttling. An outline of how shuttling proteins use nuclear transport receptors as well as nucleocytoplasmic shuttling signals for nucleocytoplasmic transport is given in the presented work. This research offers a resource for comprehending herpesvirus infection pathogenesis and formulating novel anti-viral approaches. It also explains how herpesvirus shuttling proteins contribute to efficient infection of viruses through altering their life-cycle and engaging in innate immunity.
