P3 decorate the virions; its N-terminal domain forms an antiparallel alpha-helical coiled-coil network at the surface and the C-terminal domain interacts with the C-terminal half of the coat protein. It is a DNA binding protein in which the DNA binding activity is located on its C-terminal part [1,2].
