CC   -!- FUNCTION: Assembles the procapsid by joining twelve 12S pre-assembly
CC       complex into a T=1 icosahedral particle, called 108S procapsid. Ten
CC       proteins D bind each 12S complex, which are formed by three pentamers
CC       of F, G, B protein and a H protein. The scaffolding protein is released
CC       from the provirion after genome packaging to form the mature virion.
CC       {ECO:0000250|UniProtKB:P69486}.
CC   -!- SUBUNIT: Component of the procapsid particle composed of 60 copies of
CC       the internally located B, 240 copies of the external scaffolding
CC       protein D, 60 copies of each of the viral structural proteins F and G,
CC       and 12 copies of protein H. {ECO:0000250|UniProtKB:P69486}.
CC   -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000250|UniProtKB:P69486}.
CC   -!- SIMILARITY: Belongs to the microvirus D protein family. {ECO:0000305}.
