This manuscript explores the dynamic behaviors of Pol II and Pol III puncta that encompass the SL1 and 5S genes, following up on the authors' prior studies on ATTF-6. The authors show that ATTF-6 is required for RNA Pol II but not RNA Pol III foci, demonstrating that within the gene cluster, the regulation of RNA Pol II and RNA Pol III remain distinct from each other. The study is useful for analyzing understudied gene families, but it is incomplete and needs additional edits and experiments.
