A Novel Stress Response Pathway Regulates Ribosome Biogenesis

W. Szaflarski, M. Sowinski, M. Lesniczak, S. Ojha, A. Aulas, D. Dave, S. Malla, P. Anderson, P. Ivanov, S. M. Lyons

This study identifies a novel stress response pathway, RiBiSR, that regulates rRNA processing and ribosome biogenesis independently of the ISR to conserve energy and maintain the nucleolus.

Fragmentation of extracellular ribosomes and tRNAs shapes the extracellular RNAome

J. P. Tosar, M. Segovia, F. Gambaro, Y. Akiyama, P. Fagundez, B. Costa, T. Possi, M. Hill, P. Ivanov, A. Cayota

The paper develops RI-SEC-seq to analyze nonvesicular exRNAs, revealing extracellular ribosomes and tRNAs that resist degradation and act as damage-associated molecular patterns.

Revisiting G3BP-S149 phosphorylation and its impact on stress granule assembly

M. D. Panas, N. Kedersha, T. Schulte, R. M. Branca, P. Ivanov, P. J. Anderson

The paper investigates the role of G3BP1-S149 phosphorylation in stress granule assembly, revealing that unintended mutations in engineered constructs confound previous conclusions about S149's effect.
