This study identifies polyamines as regulators of inorganic polyphosphate accumulation in E. coli during nitrogen starvation.

This study identifies polyphosphate as a structural component of filopodia that regulates cell adhesion and invasion, with implications for tumor suppression.

This study shows that paralogs H-NS and StpA form distinct condensates with different phase behaviors, enabling bacteria to adjust condensate stability for stress response.

The paper identifies polyphosphate as a scaffold for phase-separated condensates in bacteria and humans, showing its role in RNA turnover and translation.
