Genome dilution limits cell growth by modulating the activities, rather than the concentrations, of RNA polymerases and ribosomes, and is accompanied by changes in proteome composition.
N‑terminus of MSL1 protein, involved in dosage compensation in Drosophila, is required for the interaction with non-coding roX2 RNA and the assembly of the complex on the male X chromosome.

Plasmodium parasites have repurposed the heme oxygenase scaffold from its canonical heme-degrading function to fulfill an essential and adaptive role in gene expression within the apicoplast organelle.
Genetic analyses in budding yeast coupled with biochemical assays have revealed an unexpected role for the Smc5/6 complex in cellular pathways responsible for the prevention of RNA formation in genomic DNA.
