CC   -!- FUNCTION: Scaffolding protein involved in the icosahedric procapsid
CC       assembly. Coassembles with the capsid proteins to form the procapsid,
CC       in which the scaffolding protein is found within the external shell of
CC       icosahedrally arranged capsid protein subunits. In a subsequent step
CC       the scaffolding protein molecules are released from the procapsid.
CC       {ECO:0000250|UniProtKB:Q38580}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:Q38580}.
CC   -!- SIMILARITY: Belongs to the SPP1-like scaffolding protein family.
CC       {ECO:0000305}.
