T=2 icosahedral viral capsid
Cellular Component
Definition (GO:0039616 GONUTS page)
The protein coat that surrounds the infective nucleic acid in some virus particles where the subunits (capsomeres) are arranged to form an icosahedron with T=2 symmetry. The T=2 capsid is composed of 12 pentameric dimers.
Comments
