7SL RNA in vertebrate red blood cells [REPORT]

01-Jul-2018 | Gaëlle J.S. Talhouarne; Joseph G. Gall, RNA, 2018

We report that 7SL, the RNA component of the signal recognition particle (SRP), is an abundant noncoding RNA (ncRNA) in mature red blood cells (RBCs) of human, mouse, and the frog Xenopus. 7SL RNA in RBCs is not associated with the canonical proteins of the SRP. Instead, it coimmunoprecipitates ...

Assembly of the small ribosomal subunit in yeast: mechanism and regulation [REVIEW]

01-Jul-2018 | Malik Chaker-Margot, RNA, 2018

The eukaryotic ribosome is made of four intricately folded ribosomal RNAs and 79 proteins. During rapid growth, yeast cells produce an incredible 2000 ribosomes every minute. Ribosome assembly involves more than 200 trans-acting factors, intervening from the transcription of the preribosomal RNA ...

Hydrogen peroxide is a neuronal alarmin that triggers specific RNAs, local translation of Annexin A2, and cytoskeletal remodeling in Schwann cells [ARTICLE]

01-Jul-2018 | Samuele Negro; Marco Stazi; Marta Marchioretto; Toma Tebaldi; Umberto Rodella; Elisa Duregotti; Volker Gerke; Alessa ..., RNA, 2018

Schwann cells are key players in neuro-regeneration: They sense "alarm" signals released by degenerating nerve terminals and differentiate toward a proregenerative phenotype, with phagocytosis of nerve debris and nerve guidance. At the murine neuromuscular junction, hydrogen peroxide (H2O2) is a ...

Memories: Just a phase

29-Jun-2018 | Caroline Ash; Jesse Smith; Stella M. Hurtley, Science , 2018

Cell Biology Recently, several proteins have been shown to phase-separate into liquid droplets within the cell. Dine et al. found that such protein droplets exhibit a robust form of spatial memory. The droplets maintained the spatial pattern of an inhibitor of droplet formation long after the

Structures of the fully assembled Saccharomyces cerevisiae spliceosome before activation

29-Jun-2018 | Rui Bai; Ruixue Wan; Chuangye Yan; Jianlin Lei; Yigong Shi, Science , 2018

The precatalytic spliceosome (B complex) is preceded by the pre-B complex. Here we report the cryo–electron microscopy structures of the Saccharomyces cerevisiae pre-B and B complexes at average resolutions of 3.3 to 4.6 and 3.9 angstroms, respectively. In the pre-B complex, the duplex between ...

The NEDD8 E3 ligase DCNL5 is phosphorylated by IKK alpha during Toll-like receptor activation

29-Jun-2018 | Yann Thomas; Daniel C. Scott; Yosua Adi Kristariyanto; Jesse Rinehart; Kristopher Clark; Philip Cohen; Thimo Kurz, PLoS ONE, 2018

by Yann Thomas, Daniel C. Scott, Yosua Adi Kristariyanto, Jesse Rinehart, Kristopher Clark, Philip Cohen, Thimo Kurz The activity of Cullin-RING ubiquitin E3 ligases (CRL) is regulated by NEDD8 modification. DCN-like proteins promote Cullin neddylation as scaffold-like E3s. One DCNL, DCNL5, is ...

Methyl-CpG-binding (SmMBD2/3) and chromobox (SmCBX) proteins are required for neoblast proliferation and oviposition in the parasitic blood fluke Schistosoma mansoni

28-Jun-2018 | Kathrin K. Geyer; Sabrina E. Munshi; Helen L. Whiteland; Narcis Fernandez-Fuentes; Dylan W. Phillips; Karl F. Hoffmann, PLoS Pathogens, 2018

by Kathrin K. Geyer, Sabrina E. Munshi, Helen L. Whiteland, Narcis Fernandez-Fuentes, Dylan W. Phillips, Karl F. Hoffmann While schistosomiasis remains a significant health problem in low to middle income countries, it also represents a recently recognised threat to more economically-developed ...

Specific binding of PCBP1 to heavily oxidized RNA to induce cell death [Cell Biology]

26-Jun-2018 | Takashi Ishii; Hiroshi Hayakawa; Tatsuhiro Igawa; Takeshi Sekiguchi; Mutsuo Sekiguchi, Proceedings of the National Academy of Sciences current issue, 2018

The binding of human PCBP1 protein to heavily oxidized RNA triggers the induction of apoptosis-related reactions, including the activation of caspase-3 and the cleavage of PARP-1. The introduction of amino acid substitutions in the PCBP1 abolishes this, resulting in the failure of PARP-1 ...
