Minor capsid protein present in the outer capsid, which is required for adsorption of the virus onto host insect cells (Potential). Could play a role in the host plant virus induced dwarfism (By similarity). Interacts with host ent-kaurene oxidases OSKO1, OSKO2, OSKOL4 and OSKOL5; this interaction. Found in the peripheral regions of spherical cytoplasmic structures, called virus factories, that appear early after infection and are the site of viral replication and packaging. Belongs to the phytoreovirus minor outer capsid protein P2 family.
