Attaches 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 (By similarity). Homotrimer. Interacts with matrix protein (By similarity). Glycosylated by host. Glycosylation is crucial for glycoprotein export at the cell surface (By similarity). Belongs to the cytorhabdovirus glycoprotein family.
