An Interchromosomal Interaction Drives TAL1 Transcription in T-ALL Cells. Representation of the contact detected by 4C between the TAL1 promoter on chromosome 1 and the TIL16 enhancer on chromosome 16. This interchromosomal interaction depends on expression of the c-MAF transcription factor, which binds to sequences within both TIL16 and the TAL1 promoter. An intrachromsomal contact between CTCF sites downstream of TAL1 is observed by 3C. This presumably represents a CTCF-mediated structural loop.
