Enterovirus D68, a member of Enterovirus genus of the Picornaviridae family, mainly causes respiratory system-related diseases as well as neurological complications in some patients. The capsid of Enterovirus D68 virus is composed of subunit proteins (VP1, VP2, VP3, and VP4) . VP1 protein contains multiple epitopes and receptor binding sites and is often used in phylogenetic analysis of viruses. Capsid protein VP4 is released, Capsid protein VP1 N-terminus is externalized, and together, they shape a pore in the host membrane through which the viral genome is translocated into the host cell cytoplasm. In addition, after binding to the host receptor, the capsid undergoes conformational changes. Enterovirus D68 VP1 Protein (sf9, Fc) is the recombinant Virus-derived Enterovirus D68 VP1 protein, expressed by Sf9 insect cells , with C-hFc labeled tag.
