Recombinant HSV2 gG Envelope protein

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The HSV2 gG envelope protein also known as glycoprotein G plays a mechanical role in the herpes simplex virus type 2 (HSV-2). This protein is important for virus-host interactions and the initiation of infection. Glycoprotein G has a molecular mass of approximately 120 kDa. Specificity of gG is linked to its expression on the envelope of the virus enabling it to attach and penetrate host cells by recognizing cell surface receptors.

Biological function summary

Glycoprotein G functions as a determinant of serotype specificity aiding in distinguishing between HSV-1 and HSV-2 infections. It does not work alone but is part of a complex with other viral glycoproteins such as gB gC and gD. While gG itself binds less strongly it facilitates the immune evasion by cloaking other viral structures. This complex setup allows the virus to evade host immune recognition during initial stages of infection.

Pathways

The HSV2 gG protein interacts directly with host cellular pathways particularly endocytosis and viral entry pathways. It does not act in isolation but closely interacts with proteins like gD which binds to specific cellular receptors involved in viral entry. This pairing enables the virus to effectively exploit host cell machinery to propagate itself within the host.

Glycoprotein G plays a role in herpes genitalis and is linked to immune response disorders. The presence and recognition of gG are significant in the pathogenesis of HSV-2 infection. Because of its role in serotype discrimination gG is often used in serological tests to differentiate HSV-2 from HSV-1 infection. The interaction of gG with host immune pathways also links it to other viral glycoproteins potentially affecting disease outcomes and therapeutic approaches.
