| Transmission mechanism | Our data suggest that the binding of vapendavir to the capsid of the G149C isolate may be required to stabilize the viral particle and to allow efficient dissemination of the virus. |

Protein detail:
| Protein name | Capsid Protein VP1 |
| Uniprot protein ID | P07210 |
| Protein length | 298 amino acids |
| Protein description | Capsid protein VP1 forms an icosahedral capsid of pseudo T=3 symmetry with capsid proteins VP2 and VP3. The capsid is 300 Angstroms in diameter, composed of 60 copies of each capsid protein and enclosing the viral positive strand RNA genome. Capsid protein VP1 mainly forms the vertices of the capsid. Capsid protein VP1 interacts with host cell receptor to provide virion attachment to target host cells. This attachment induces virion internalization. Tyrosine kinases are probably involved in the entry process. After binding to its receptor, the capsid undergoes conformational changes. Capsid protein VP1 N-terminus (that contains an amphipathic alpha-helix) and capsid protein VP4 are externalized. Together, they shape a pore in the host membrane through which viral genome is translocated to host cell cytoplasm. After genome has been released, the channel shrinks. |

| Evidence | Interestingly, we also observed mutations located outside the pocket (K167E in EV-D68 and G149C in hRV3) that contribute to the resistant phenotype. |
