Function

Forms the virion spikes together with glycoprotein G1. The glycoprotein spike trimers are connected to the underlying matrix. Class I viral fusion protein that directs fusion of viral and host endosomal membranes, leading to delivery of the nucleocapsid into the cytoplasm.

Biological Context

Subcellular Location: Virion membrane (Single-pass membrane protein); Host endoplasmic reticulum membrane (Single-pass membrane protein); Host Golgi apparatus membrane (Single-pass membrane protein); Host cell membrane (Single-pass membrane protein)

Function

Forms the virion spikes together with glycoprotein G1. The glycoprotein spike trimers are connected to the underlying matrix. Class I viral fusion protein that directs fusion of viral and host endosomal membranes, leading to delivery of the nucleocapsid into the cytoplasm (PubMed:16731928). Membrane fusion is mediated by irreversible conformational changes induced by acidification

Subunit

Homotrimer (PubMed:16731928). Interacts with the stable signal peptide. In pre-fusion state, G2 homotrimers bind G1 homotrimers via ionic interactions. Part of the GP complex (GP-C) together with glycoprotein G1 and the stable signal peptide. Acidification in the endosome triggers rearrangements, which ultimately leads to a 6 helix bundle formed by the two heptad repeat domains (HR1 and HR2) in post-fusion state. The GP-complex interacts with protein Z, which interacts with ribonucleocapsid; these interactions may induce virion budding (PubMed:17581989)
