Protein

Capsid protein

Gene

ORF2

Organism
San Miguel sea lion virus serotype 1 (SMSV-1) (SMSV serotype 1)
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

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 (By similarity).By similarity
