Our first paper came out in Molecular Cell today! This is Shasha’s work together with the Tjian/Darzacq Lab at UC Berkeley. We report that endogenous gene transcription requires narrow optimum of transcription factor (TF) low-complexity domain (LCD) multivalent interactions, and phase separation can be counterproductive (A). We also show that mislocalized TF LCD multivalent interactions can outcompete stochiometric TF-DNA binding and sequester a TF away from its target genes to distrupt its functions, indicating a new therapeutic strategy for targeting disease-causing TFs, e.g., EWS::FLI1 (B). Furthermore, we provide proof-of-concept demonstration that single-molecule measurements of protein diffusion rates can serve as an effective means for detecting phase separation in vivo. We detected a slower TF diffusion in the phase-separated nucleolus than in the nucleoplasm (C). Check out the details in "Tuning levels of low-complexity domain interactions to modulate endogenous oncogenic transcription."
Shawn Yoshida (BMB, G1) officially joins us as our second graduate student today! Shawn is originally from Tokyo, Japan and grew up in Illinois.
