CC   -!- FUNCTION: P2 proheads and capsids consist primarily of N*, a 36.7 kDa
CC       protein and two minor components, H1 (39 kDa) and H2 (38.6 kDa).
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC   -!- PTM: N*, H1 and H2 all derive from full-length N protein by N-terminal
CC       processing. {ECO:0000269|PubMed:8874520}.
CC   -!- SIMILARITY: Belongs to the P2-like viruses major capsid protein family.
CC       {ECO:0000305}.
