Schematic representations of the BLV genome structure (a) and viral particle (b). The structural and enzymatic genes, gag, pro, pol, and env; regulatory genes, tax and rex; accessory genes R3 and G4; and microRNA (miRNA) are indicated in (a). Proteins encoded by structural and enzymatic genes, including the Env glycoproteins (gp51 and gp30) encoded by the env gene, the Gag proteins (p12, p24, and p15) encoded by the gag gene, reverse transcriptase and integrase (RT-IN) encoded by the pol gene, and protease (Pro) encoded by the pro gene are indicated in (b)
