CC   -!- FUNCTION: Involved, together with A1 protein, in the second step
CC       transfer (SST) which allows the completion of viral DNA into the host
CC       cell. {ECO:0000250|UniProtKB:P23541}.
CC   -!- SUBUNIT: Interacts with A1 protein; the two proteins form
CC       heterooligomers. {ECO:0000250|UniProtKB:P23541}.
CC   -!- MISCELLANEOUS: This gene is part of the long terminal repeats present
CC       at both ends of the viral genome and is thus duplicated.
CC       {ECO:0000250|UniProtKB:P23541}.
CC   -!- SIMILARITY: Belongs to the T5likevirus A2 protein family.
CC       {ECO:0000305}.
