CC   -!- FUNCTION: Major core structural protein. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250}. Note=Localizes to the
CC       virion core. {ECO:0000250}.
CC   -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC   -!- PTM: Undergoes morphogenesis-associated proteolysis which cleaves the
CC       28 kDa to a 25-kDa product. Proteolytic cleavage of major core proteins
CC       P4a (A10L), P4b (A3L), and VP8 (L4R), which occurs at a late stage of
CC       core formation, is required for production of infectious mature virions
CC       (MV) (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the chordopoxvirinae VP8 family. {ECO:0000305}.
