RNA polymerases II and III form dynamic, spatially distinct nuclear foci at the C. elegans 5S rDNA-SL1 gene cluster, with Pol II foci being temperature-sensitive.
- Why it matters: Understanding how transcription machinery is organized at gene clusters is crucial for revealing gene expression regulation, yet this spatial organization remains poorly characterized.
- What they did: The study used imaging and molecular approaches to show that Pol II and Pol III assemble into regulated, distinct foci within the nucleus, with their formation influenced by cell cycle and temperature.
- The result: These findings demonstrate that the spatial and temporal organization of RNA polymerases at gene clusters controls transcription dynamics, impacting gene expression regulation in living cells.
