Viral protein involved in the merging of the virion membrane with the host membrane during viral penetration or egress in host cell. Viral fusion proteins drive this fusion reaction by undergoing a major conformational change that is triggered by interactions with the target cell. The specific trigger depends on the virus and can be exposure to low pH in the endocytic pathway or interaction of the virion with the host receptor(s).
