Our findings indicate that individual stalled ribosomes are the potential signal for ribosome dysfunction, leading to accelerated turnover of the ribosome itself.įrom the Graduate School of Pharmaceutical Sciences, Tohoku University, Sendai 980-8578, Japan Division of RNA and Gene Regulation, Institute of Medical Science, The University of Tokyo, Minato-ku 108-8639, Japan. The military has a chance of stopping the undead, but not in that way. A life in which each possible variation counts Those who have passed on have risen, and human progress has regressed. Cryo-EM structures of Fap1-bound ribosomes elucidated Fap1 probing the mRNA simultaneously at both the entry and exit channels suggesting an mRNA stasis sensing activity, and Fap1 sterically hinders the formation of canonical collided di-ribosomes. In 2018, Microsoft Studios released State of Decay 2, an action-adventure role-playing video game (RPG) for personal computers. Ribosome profiling revealed an enrichment of Fap1 at the translation initiation site but also an association with elongating individual ribosomes. Here, focusing on noncolliding stalling exhibited by decoding-defective ribosomes, we identified Fap1 as a stalling sensor triggering 18S nonfunctional rRNA decay via polyubiquitination of uS3. How ribosome stalling is resolved without collisions, however, has remained elusive. Biologically Interesting Molecule Reference Dictionary (BIRD)Ĭells can respond to stalled ribosomes by sensing ribosome collisions and employing quality control pathways.
