    RNAP II CTD tyrosine 1 performs diverse functions in vertebrate cells

    Jing-Ping Hsin, Wencheng Li ... James L Manley
    Phosphorylation of tyrosine 1 in the carboxy-terminal domain (CTD) of the largest subunit of RNA Polymerase (RNAP) II functions to stabilize this domain, and facilitates turnover of upstream antisense RNAs.

    Tyrosine phosphorylation of RNA polymerase II CTD is associated with antisense promoter transcription and active enhancers in mammalian cells

    Nicolas Descostes, Martin Heidemann ... Jean-Christophe Andrau
    Genome-wide analysis reveals novel functions for a post-translational modification to the carboxy-terminal domain (CTD) of RNA Polymerase II in mammals.

    Gene age shapes the transcriptional landscape of sexual morphogenesis in mushroom-forming fungi (Agaricomycetes)

    Zsolt Merényi, Máté Virágh ... László G Nagy
    Allele-specific expression, natural antisense transcripts, and developmental gene expression, but not RNA editing or developmental hourglass, act in concert to shape the transcriptome during the fruiting body formation of complex multicellular fungi.

    Translation of dipeptide repeat proteins in C9ORF72 ALS/FTD through unique and redundant AUG initiation codons

    Yoshifumi Sonobe, Soojin Lee ... Paschalis Kratsios
    Mutational analysis in cell-based models of C9ORF72 ALS/FTD identifies canonical translation initiation codons (AUG) on the antisense CCCCGG transcript as initiation sites for synthesis of neurotoxic dipeptide repeat proteins.

    RNase III-mediated processing of a trans-acting bacterial sRNA and its cis-encoded antagonist

    Sarah Lauren Svensson, Cynthia Mira Sharma
    Functional characterization of a pair of cis-encoded antisense RNAs reveals a role for RNase III and antisense regulation in the biogenesis and regulatory activity of a bacterial virulence factor-regulating small RNA.

    CRISPRi is not strand-specific at all loci and redefines the transcriptional landscape

    Françoise S Howe, Andrew Russell ... Jane Mellor
    CRISPR interference (CRISPRi), which uses small guide RNAs to target catalytically dead Cas9 protein to chromatin, disrupts existing transcription units and generates new sites for initiation and termination of transcription on both strands of DNA.

    Endogenous p53 expression in human and mouse is not regulated by its 3′UTR

    Sibylle Mitschka, Christine Mayr
    The endogenous 3′UTR does not regulate TP53 mRNA or protein level and the 3′UTR is repressive when used alone in reporters, but addition of the coding region has a dominant repressive effect.

    Clp protease and antisense RNA jointly regulate the global regulator CarD to mediate mycobacterial starvation response

    Xinfeng Li, Fang Chen ... Jin He
    Under starvation conditions, anti-carD antisense RNA and Clp protease work together to decrease the CarD level to mediate the adaptation and survival of mycobacterial cells.

    p50-associated COX-2 extragenic RNA (PACER) activates COX-2 gene expression by occluding repressive NF-κB complexes

    Michal Krawczyk, Beverly M Emerson
    A long non-coding RNA removes the transcriptional repressor p50 to regulate recruitment of co-activator p300 and RNA Polymerase II complexes to activate the COX-2 gene in human mammary epithelial cells and macrophages.

    Identification of an LGP2-associated MDA5 agonist in picornavirus-infected cells

    Safia Deddouche, Delphine Goubau ... Caetano Reis e Sousa
    A viral RNA has been identified as a specific MDA5 agonist in cells infected with encephalomyocarditis virus.
