Glycoprotein (UniProt: P03524) is encoded by the G gene in Rabies virus, strain ERA.
Glycoprotein is a single-pass type I membrane protein that belongs to the lyssavirus glycoprotein family.
It attached the virus to host cellular receptor, inducing endocytosis of the virion.
In the endosome, the acidic pH induces conformational changes in the glycoprotein trimer, which trigger fusion between virus and cell membrane.
The muscular form of the nicotinic acetylcholine receptor (nAChR), the neuronal cell adhesion molecule (NCAM), and the p75 neurotrophin receptor (p75NTR) are reported to bind glycoprotein and thereby facilitate rabies virus entry into cells.
Glycoprotein is synthesized with a signal peptide (aa 1-19), which is subsequently cleaved off in the mature form.
Its structure includes a virion surface (aa 20-459), helical region (aa 460-480) and an intravirion (aa 481-524).
Arginine 352 is reported to be involved in Rabies virus pathogenicity and its mutation attenuates the virus.
Glycoprotein is glycosylated and palmitoylated by host and glycosylation is considered to be crucial for glycoprotein export at the cell surface.
046247X is a serum-free version and is shown to neutralize Rabies Virus, CVS-11 strain.
Applications:Suitable for use in Flow Cytometry, ELISA and Neutralization.
