[[http://www.uniprot.org/uniprot/CAPSD_FCVF9 CAPSD_FCVF9]] 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 to feline junctional adhesion molecule A (F11R) and/or to alpha-2,6-linked sialic acid. Once attached, the virion is endocytosed. Acidification of the endosome induces conformational change of capsid protein thereby injecting virus genomic RNA into host cytoplasm. [[http://www.uniprot.org/uniprot/VP2_FCVF9 VP2_FCVF9]] Minor structural protein present in one or two copies per virion. Does not seem to play a role in capsid assembly, but is essential for production of infectious virus (By similarity). [[http://www.uniprot.org/uniprot/JAM1_FELCA JAM1_FELCA]] Seems to play a role in epithelial tight junction formation. Appears early in primordial forms of cell junctions and recruits PARD3. The association of the PARD6-PARD3 complex may prevent the interaction of PARD3 with JAM1, thereby preventing tight junction assembly. Plays a role in regulating monocyte transmigration involved in integrity of epithelial barrier. Ligand for integrin alpha-L/beta-2 involved in memory T-cell and neutrophil transmigration. Involved in platelet activation.[UniProtKB:O88792][UniProtKB:Q9Y624]  (Microbial infection) May act as a cellular receptor for calicivirus.<ref>PMID:16611908</ref> <ref>PMID:17913818</ref>  (Microbial infection) In case of orthoreovirus infection, serves as receptor for the virus.<ref>PMID:11239401</ref>
