Broad forms longer-lived transcription hubs at the hnt locus than Notch coactivator Mastermind, and this hub handover is linked to a sustained Notch response phase.
- Why it matters: Cells need ways to keep gene programs active after an initial Notch signal fades, but how transcription hubs change over time to sustain output is unclear.
- What they did: Using live imaging of hnt transcription and transcription complexes at target loci, the study measured two phases and tracked transcription factor enrichment and hub lifetimes, including intermediate hubs containing both Broad and Mam.
- The result: The first, Notch-controlled probabilistic phase transitions to a Broad-controlled sustained phase, with Broad’s more stable chromatin association producing longer-lasting hubs and enabling temporal progression of transcription.
