The BR-body proteome contains a complex network of protein-protein and protein-RNA interactions

V. Nandana, I. W. Rathnayaka-Mudiyanselage, N. S. Muthunayake, A. Hatami, C. B. Mousseau, L. A. Ortiz-Rodriguez, J. Vaishnav, M. Collins, A. Gega, K. S. Mallikaarachchi, H. Yassine, A. Ghosh, J. S. Biteen, Y. Zhu, M. M. Champion, , J. M. Schrader

The paper identifies 111 proteins enriched in bacterial RNP bodies (BR-bodies) and shows they form a complex network of protein-protein and protein-RNA interactions that regulate BR-body phase separation and RNA processing.
