Capsid protein VP1

UniProtKB accession:  P27406

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Self assembles to form an icosahedral capsid with a T=3 symmetry, about 38 nm in diameter, and consisting of 180 capsid proteins (PubMed:30626974). A smaller form of capsid with a diameter of 23 nm might be capsid proteins assembled as icosahedron with T=1 symmetry. The capsid encapsulates the genomic RNA and is decorated with VP2 proteins (PubMed:1633955). Attaches virion to target cells by binding to feline junctional adhesion molecule A (F11R) and/or to alpha-2,6-linked sialic acid (PubMed:17170450, PubMed:17913818, PubMed:30626974). Once attached, the virion is endocytosed. Acidification of the endosome induces conformational change of capsid protein thereby injecting virus genomic RNA into host cytoplasm (Probable).
