VACWR074 is a recombinant protein derived from the Vaccinia virus (VACV), a member of the Poxviridae family. Vaccinia virus has been extensively studied due to its historical role as the live vaccine used to eradicate smallpox. The virus’s large double-stranded DNA genome encodes numerous proteins that modulate host immune responses and facilitate viral replication. VACWR074. specifically, is associated with the Western Reserve (WR) strain, a laboratory-adapted variant known for its virulence in murine models. The protein is encoded by the WR074 gene, which is homologous to the Copenhagen strain’s C12L gene, though its exact function remains partially characterized.
Studies suggest that VACWR074 may play a role in immune evasion, a common strategy for poxviruses to establish infection. It is hypothesized to interfere with host antiviral signaling pathways, potentially targeting components like NF-κB or interferon responses. Structural analyses predict it to be a soluble or membrane-associated protein with possible functional domains involved in protein-protein interactions. Recombinant VACWR074 is often expressed in heterologous systems (e.g., E. coli or mammalian cells) for functional studies, enabling researchers to dissect its biochemical properties and interactions with host factors.
Interest in VACWR074 also stems from its potential applications in vaccine development and immunotherapy. As Vaccinia-based vectors are explored for recombinant vaccines against infectious diseases or cancer, understanding viral immunomodulatory proteins like VACWR074 becomes critical for optimizing safety and efficacy. Additionally, studying such proteins provides insights into host-pathogen dynamics, aiding the design of broad-spectrum antiviral strategies. Despite progress, further research is needed to fully elucidate its mechanisms and therapeutic relevance.
