Out now in Science! Our study challenges long-standing assumptions about transcription factor specificity in eukaryotes. Novel single-molecule measurements of TF behavior in living cells reveal an independence of locus-specific binding from DNA sequence recognition.🧵 www.science.org/doi/10.1126/...

Unstructured transcription factor interactions enable emergent specificity

How intrinsically disordered regions (IDRs) shape chromatin binding and nuclear organization of transcription factors (TFs) remains unclear. We used proximity-assisted photoactivation (PAPA), a single...
