== Function ==
[https://www.uniprot.org/uniprot/CAPSD_NVN68 CAPSD_NVN68] Capsid protein self assembles to form an icosahedral capsid with a T=3 symmetry, about 38 nm in diameter, and consisting of 180 capsid proteins. A smaller form of capsid with a diameter of 23 nm might be capsid proteins assembled as icosahedron with T=1 symmetry. The capsid encapsulate the genomic RNA and VP2 proteins. Attaches virion to target cells by binding histo-blood group antigens present on gastroduodenal epithelial cells.<ref>PMID:16840313</ref>   Soluble capsid protein may play a role in viral immunoevasion.<ref>PMID:16840313</ref>
