CC   -!- FUNCTION: Scaffolding protein involved in the icosahedric procapsid
CC       assembly. Coassembles with the capsid proteins to form the procapsid.
CC       The scaffolding protein is found within the capsid as a serie of
CC       concentric shells. During DNA packaging, the scaffolding protein
CC       molecules are released from the procapsid.
CC       {ECO:0000250|UniProtKB:P13848}.
CC   -!- SUBUNIT: Homodimer. Interacts non-specifically with DNA; probably binds
CC       DNA in the early stages of DNA packaging.
CC       {ECO:0000250|UniProtKB:P13848}.
CC   -!- SUBCELLULAR LOCATION: Note=Present in about 147 copies in the prohead
CC       but not present in mature virions. {ECO:0000250|UniProtKB:P13848}.
CC   -!- SIMILARITY: Belongs to the phi29likevirus scaffolding protein family.
CC       {ECO:0000305}.
