Major envelope glycoprotein

UniProtKB accession:  P17501

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Class III viral fusion protein. Envelope phosphoglycoprotein which mediates the fusion of viral and host endosomal membranes leading to virus entry into the host cell. After receptor-mediated internalization of the virus, gp64 undergoes conformational change into a fusion-competent state at low pH, and the nucleocapsid is released into the cytoplasm after cell fusion. May also play role in budding.
