Synthesis of the various HBZ isoforms. Cell extracts were prepared from 293T cells transfected with 4 μg pcDNA3.1-Myc-His HBZ, pcDNA3.1-Myc-His HBZ SP1, pcDNA3.1-Myc-His HBZ SP2 or the empty vector (-). HBZ isoforms were detected by Western blot using anti-Myc antibodies. The position of the SP1- and SP2-derived HBZ isoforms is indicated by arrows.
