D13L recombinant protein is derived from the vaccinia virus (VACV), a member of the Poxviridae family. The D13L gene encodes the D13 protein, a major structural component critical for virion morphogenesis. Discovered as a key player in viral assembly, D13 forms a hexagonal lattice scaffolding that shapes the immature virion (IV) during the early stages of VACV replication. Its structural role was elucidated through cryo-electron microscopy and crystallography studies, revealing its resemblance to capsid proteins of icosahedral viruses, despite poxviruses lacking a traditional capsid.
The D13 protein is a 62 kDa polypeptide that oligomerizes into trimers, creating a curved scaffold to guide membrane curvature and IV formation. It interacts with viral membrane proteins (e.g., A36) and the viral A32 ATPase, coordinating membrane remodeling and genome packaging. Notably, D13 is dispensable for viral replication but essential for producing infectious mature virions (MV), making it a target for antiviral strategies. Rifampicin, a well-known antibiotic, inhibits VACV assembly by binding to D13. underscoring its functional significance.
Recombinant D13L protein is produced via heterologous expression systems (e.g., E. coli or baculovirus) for structural and functional studies. It serves as a tool to investigate poxvirus assembly mechanisms, screen antiviral compounds, and develop vaccines. As VACV is closely related to variola virus (the causative agent of smallpox), understanding D13's role has implications for combating orthopoxvirus infections. Additionally, recombinant D13 is used in antibody production for diagnostic assays and as an antigen in subunit vaccine research. Its conserved nature across poxviruses makes it a valuable target for broad-spectrum antiviral research, bridging fundamental virology and translational applications.
