Product of a dubious gene prediction. AC5 is located inside the CP gene but in the opposite orientation and has been reported for ICMV and PHV in 1993 and recently for ToCMoV. Based on the domain prediction for this protein, numerous AC5 sequences have been deposited in the nucleotide databases. It is not proved that this ORF is transcribed and translated and most of the time, it is not cited in the recent literature on geminiviruses. Its significance remains to be determined.
