Thanks Genes & Development for using our work of TGF-β induced MLL4 recruitment as cover page 📓🧬. We reveal a novel role for the histone methyltransferase MLL4 (KMT2D) in transcriptional responses to TGF-β. We show that MLL4 is recruited to TGF-β target genes including JUNB while TGF-β treatment.

Integrator loss leads to dsRNA formation that triggers the integrated stress response
Integrator (INT) prevents the escape of immature RNAPII to ensure full-length mRNA production. INT deficiency causes defects in RNAPII maturation that lead to premature termination, accumulation of immunogenic dsRNA, and activation of the integrated stress response (ISR) observed in patient cells.
