Capsid protein self-assembles to form an icosahedral capsid with a T=7 symmetry, about 69 nm in diameter, and consisting of 60 capsid proteins hexamers and 11 pentamers. The capsid encapsulates the genomic DNA. Homomultimer. Main component of the capsid. Probably cleaved by the viral protease during maturation. Belongs to the Skunalikevirus capsid protein family.
