Fusion transcripts in normal prostate tissues. A: Fusion transcripts result from continuous transcription of two contiguous genes. Schematic diagrams of TTTY15 and USP9Y genomes, fusion transcripts, and predicted translation products. Blue arrow indicates fusion breakpoint in the genome. Transcription direction is indicated by black arrow. Translation start site is indicated by 90° arrow. B: Fusion transcripts result from noncontiguous transcription. Schematic diagrams of MALAT1, WDR74, and TTN genomes, fusion transcripts, and predicted translation products. Blue arrow indicates fusion breakpoint in the genome. Transcription direction is indicated by black arrow. Translation start site is indicated by 90° arrow.
