    Robust T cell activation requires an eIF3-driven burst in T cell receptor translation

    Dasmanthie De Silva, Lucas Ferguson ... Jamie HD Cate
    Binding of the translation initiation factor eIF3 to the messenger RNAs encoding the T cell receptor subunits alpha and beta is required to drive a short burst in their translation and promote a strong T cell response.

    RNA-binding protein Elavl1/HuR is required for maintenance of cranial neural crest specification

    Erica J Hutchins, Shashank Gandhi ... Marianne E Bronner
    The RNA-binding protein Elavl1 directly binds to and stabilizes a single gene product—Draxin mRNA—to prevent premature delamination and maintain specification in cranial neural crest.

    Differential translation of mRNA isoforms underlies oncogenic activation of cell cycle kinase Aurora A

    Roberta Cacioppo, Hesna Begum Akman ... Catherine Lindon
    Post-transcriptional regulation of Aurora Kinase A (AURKA) through alternative polyadenylation of its mRNA determines miRNA influence and is a feature of cell cycle-specific AURKA expression whose impairment leads to acquisition of cancer phenotypes.

    Regulation of alternative polyadenylation by Nkx2-5 and Xrn2 during mouse heart development

    Keisuke Nimura, Masamichi Yamamoto ... Yasufumi Kaneda
    A tissue-specific transcription factor is involved in the regulation of alternative polyadenylation in conjunction with a transcription termination factor.

    Ribosome recycling is not critical for translational coupling in Escherichia coli

    Kazuki Saito, Rachel Green, Allen R Buskirk
    Without ribosome recycling factor, ribosomes in Escherichia coli accumulate in 3'-UTRs and queue upstream of stop codons, but no effects were observed on the translational coupling of neighboring genes.

    SAM homeostasis is regulated by CFIm-mediated splicing of MAT2A

    Anna M Scarborough, Juliana N Flaherty ... Nicholas K Conrad
    The 3'-end formation complex CFIm regulates S-adenosylmethionine (SAM) homeostasis by promoting the splicing of the SAM synthetase transcript, MAT2A.

    Inhibition of post-termination ribosome recycling at premature termination codons in UPF1 ATPase mutants

    Lucas D Serdar, DaJuan L Whiteside ... Kristian E Baker
    Nucleotide resolution mapping of ribosome-bound RNA decay fragments in yeast cells expressing ATPase-deficient UPF1 reveals 3' UTR bound ribosomes and a role for UPF1 in post-termination ribosome recycling.

    LARP1 functions as a molecular switch for mTORC1-mediated translation of an essential class of mRNAs

    Sungki Hong, Mallory A Freeberg ... Ken Inoki
    LARP1 turns off and on the translation of an essential class of mRNAs by acting as a key effecter and regulator for mTORC1.

    Genetic and pharmacological evidence for kinetic competition between alternative poly(A) sites in yeast

    Rachael Emily Turner, Paul F Harrison ... Traude H Beilharz
    The natural compounds cordycepin and mycophenolic acid stimulate alternative polyadenylation through opposing effects on transcriptional rate.

    Eukaryotic initiation factor EIF-3.G augments mRNA translation efficiency to regulate neuronal activity

    Stephen M Blazie, Seika Takayanagi-Kiya ... Yishi Jin
    The eIF3 translation initiation complex exerts specific regulation on neuronal protein levels by targeting mRNAs with GC-rich 5' UTR.
