Protein
Major envelope glycoprotein
Organism
Autographa californica nuclear polyhedrosis virus
Function
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.
Similarity
Belongs to the baculoviridae gp64 family.
