    Functional roles of Mg2+ binding sites in ion-dependent gating of a Mg2+ channel, MgtE, revealed by solution NMR

    Tatsuro Maruyama, Shunsuke Imai ... Masanori Osawa
    Nuclear magnetic resonance analysis revealed the structural and dynamical changes in MgtE during the channel closure caused by the cooperative Mg2+-binding, which had remained undescribed only by a static crystal structure.

    Loss of MGA repression mediated by an atypical polycomb complex promotes tumor progression and invasiveness

    Haritha Mathsyaraja, Jonathen Catchpole ... Robert N Eisenman
    The MYC transcription factor network member MGA is a subunit of a non-canonical Polycomb complex, which, when inactivated, accelerates tumorigenesis in mouse models of cancer and proliferation in colon organoids.

    A resource-rational theory of set size effects in human visual working memory

    Ronald van den Berg, Wei Ji Ma
    Set size effects in visual working memory are explained as a resource-rational trade-off between an error-based behavioral cost and a neural encoding cost.

    Density-dependent resistance protects Legionella pneumophila from its own antimicrobial metabolite, HGA

    Tera C Levin, Brian P Goldspiel, Harmit S Malik
    Legionella pneumophila can be inhibited by its own antimicrobial, HGA (homogentisic acid), but its density-dependent resistance to HGA restricts the potential for self-harm.

    m6A modifications regulate intestinal immunity and rotavirus infection

    Anmin Wang, Wanyiin Tao ... Shu Zhu
    RNA m6A level is dually regulated during RV infection and development, METTL3 deficiency in IECs results in increased resistance to rotaviral infection through reduced m6A modificaitons on Irf7.

    N6-methyladenosine (m6A) reader Pho92 is recruited co-transcriptionally and couples translation to mRNA decay to promote meiotic fitness in yeast

    Radhika A Varier, Theodora Sideri ... Folkert J van Werven
    N6-methyladenosine (m6A) reader Pho92 is directed by Paf1C to meiotic mRNAs in an m6A-dependent and independent manner and promotes CCR4-NOT-mediated mRNA decay of m6A modified transcripts contingent on translation.

    Nuclear m6A reader YTHDC1 promotes muscle stem cell activation/proliferation by regulating mRNA splicing and nuclear export

    Yulong Qiao, Qiang Sun ... Huating Wang
    YTHDC1 is an essential factor controlling satellite cell regenerative ability through multifaceted gene regulatory mechanisms in myoblast cells.

    Neural crest-specific deletion of Rbfox2 in mice leads to craniofacial abnormalities including cleft palate

    Dasan Mary Cibi, Masum M Mia ... Manvendra K Singh
    The identification of the splicing code and all the required components of alternative splicing will be crucial for a comprehensive understanding of this process in the neural crest cell biology.

    Stimulation strength controls the rate of initiation but not the molecular organisation of TCR-induced signalling

    Claire Y Ma, John C Marioni ... Arianne C Richard
    The strength of TCR signalling determines the rate at which cells initiate a tightly coordinated signalling programme, without altering its organization.

    Organisms with alternative genetic codes resolve unassigned codons via mistranslation and ribosomal rescue

    Natalie Jing Ma, Colin F Hemez ... Farren J Isaacs
    Cells resolve unassigned codons with near-cognate suppression, frameshifting, and ribosomal rescue mechanisms, demonstrating that unassigned codons are permissible in both natural and engineered genetic codes as barriers to horizontal gene transfer.
