The function of transcription factors is conveyed through intrinsically disordered regions (IDRs) containing activation or repression domains, but the lack of quantitative structural ensemble models prevents their mechanistic decoding. Here, the authors use several methods to demonstrate that DNA binding can lead to complex changes in the IDR ensemble and accessibility on the example of the C-terminal IDR of pioneer factor Sox2.
