During eukaryotic transcription elongation, RNA polymerase II (RNAP2) is regulated by a chorus of factors. Here we identified a common binary interaction module consisting of TFIIS N-terminal domains (TNDs) and natively unstructured TND-interacting motifs (TIMs). This module was conserved among the elongation machinery and linked complexes including TFIIS, Mediator, super elongation complex, elongin, IWS1, SPT6, PP1/PNUTS phosphatase, H3K36me3 readers, and other factors. Using NMR, live-cell microscopy, and mass spectrometry, we revealed the structural basis for these interactions and found that TND-TIM sequences were necessary and sufficient to induce strong and specific co-localization in the crowded nuclear environment. Disruption of a single TIM in IWS1 induced robust changes in gene expression and RNAP2 elongation dynamics, underscoring the functional importance of TND-TIM surfaces for transcription elongation.
