The 3' open reading frame is the structural capsid protein, cap, which can be spliced to form two RNAs, one for virion protein 1 (VP1) and the other goes on to eventually make VP2 and VP3. The second gene, rep, can be spliced into four different, nonstructural, regulatory proteins that all aid in the genome replication.
