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. Membrane fusion is mediated by irreversible conformational changes induced by acidification

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)

Subunit

Homotrimer. 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
