CC   -!- FUNCTION: DNA-binding protein that plays a critical role in nucleoid
CC       compaction, genome replication and DNA replication and transcription
CC       (By similarity). Binds to both ssDNA and dsDNA with a binding site
CC       covering about 15 nucleotides (By similarity). Displays DNA-
CC       supercoiling activity only when associated with the viral DNA
CC       topoisomerase 2 (By similarity). {ECO:0000250|UniProtKB:P68742}.
CC   -!- ACTIVITY REGULATION: Stilbene derivatives SD1 and SD4 disrupt the
CC       binding between pA104R and DNA and inhibit the viral replication in
CC       primary alveolar macrophages. {ECO:0000250|UniProtKB:P68742}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P68742}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250|UniProtKB:P68742}. Note=Found
CC       in association with viral nucleoid. {ECO:0000250|UniProtKB:P68742}.
CC   -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC       {ECO:0000250|UniProtKB:P68742}.
CC   -!- MISCELLANEOUS: Host antibody response against A104R protein is higher
CC       in asymptomatic than in chronically infected hosts.
CC       {ECO:0000250|UniProtKB:P68742}.
CC   -!- SIMILARITY: Belongs to the bacterial histone-like protein family.
CC       {ECO:0000305}.
