About Phlebovirus Glycoprotein Gc

Phleboviruses are enveloped RNA viruses belonging to the family Phenuiviridae and include important human and veterinary pathogens such as Rift Valley fever virus (RVFV), Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV), and Heartland virus. Viral infection is mediated by two envelope glycoproteins, Gn and Gc, which function together to facilitate host-cell attachment, viral entry, membrane fusion, and virion assembly.

Glycoprotein Gc is the principal viral fusion protein responsible for mediating fusion between the viral envelope and host-cell membranes during infection. Following receptor-mediated endocytosis and exposure to the acidic environment of endosomes, Gc undergoes extensive conformational changes that drive membrane fusion and enable release of the viral genome into the host cell cytoplasm. Because of its essential role in viral entry, Gc has become a major focus of structural biology, antiviral drug discovery, vaccine development, and neutralizing antibody research.

eEnzyme's recombinant Phlebovirus Glycoprotein Gc is expressed in mammalian cells and is suitable for antibody generation, vaccine research, receptor-binding studies, structural biology investigations, and immunological assay development. The protein can be utilized to support studies of viral entry mechanisms, membrane fusion, host-pathogen interactions, epitope mapping, and immune response characterization.

Applications of Phlebovirus Glycoprotein Gc

• Vaccine development and antigen evaluation
• Neutralizing antibody discovery and characterization
• Viral entry and membrane fusion studies
• Structural biology and fusion mechanism investigations
• Receptor-binding research
• ELISA, Western blot, and immunological assays

Biological Significance of Glycoprotein Gc

Glycoprotein Gc functions as the viral membrane fusion protein that enables phleboviruses to enter susceptible host cells. During infection, low endosomal pH triggers structural rearrangements in Gc that promote fusion between viral and cellular membranes. Because this fusion process is essential for viral replication, Gc represents a highly attractive target for antiviral therapeutics, vaccine antigens, and broadly neutralizing antibodies. Structural studies have demonstrated that the fusion mechanism of phlebovirus Gc shares similarities with fusion proteins found in several other medically important enveloped viruses.
