From: Regulation of FeLV-945 by c-Myb binding and CBP recruitment to the LTR
Diagram of the U3 region of the FeLV-945 LTR, indicating the transcriptional enhancer (hatched box), 21-bp triplication (open boxes) and transcriptional promoter (Pro). Below the diagram is shown the sequence of the 21-bp triplication, indicating putative binding sites for the c-Myb transcription factor formed across the repeat junctions. The c-Myb binding site consensus occurs in the negative strand.
