    Loss of Doc2b does not influence transmission at Purkinje cell to deep nuclei synapses under physiological conditions

    Mehak M Khan, Wade G Regehr
    Eliminating the calcium-binding protein Doc2b does not alter transmission at a mature synapse under physiological conditions, counter to the prevailing view of Doc2b based on cultured neurons.

    The dynamic interplay of host and viral enzymes in type III CRISPR-mediated cyclic nucleotide signalling

    Januka S Athukoralage et al.
    The dynamic interplay between type III CRISPR enzymes governs cyclic nucleotide levels and infection outcomes in virus-host conflict.

    HDX-MS reveals nucleotide-dependent, anti-correlated opening and closure of SecA and SecY channels of the bacterial translocon

    Zainab Ahdash et al.
    Hydrogen-deuterium exchange mass spectrometry reveals nucleotide-driven conformational regulation of Sec protein-channel to help impose directionality for protein transport through the Sec complex.

    Activation of a nucleotide-dependent RCK domain requires binding of a cation cofactor to a conserved site

    Celso M Teixeira-Duarte et al.
    Cations are essential cofactors in the ATP activation mechanism of the KtrAB cation channel and appear to be cofactors of many other nucleotide-dependent RCK domains.

    Mechanisms of nucleotide selection by telomerase

    Matthew A Schaich et al.
    The roles of key telomerase active site residues were elucidated to determine how telomerase selects the correct from the incorrect nucleotide to maintain telomere integrity.

    Protein gradients on the nucleoid position the carbon-fixing organelles of cyanobacteria

    Joshua S MacCready et al.
    Carboxysomes, the carbon-fixation machinery of cyanobacteria, are equidistantly-positioned by dynamic gradients of the protein McdA on the nucleoid that emerge through interaction with a previously unidentified carboxysome factor, McdB.

    Conserved and divergent development of brainstem vestibular and auditory nuclei

    Marcela Lipovsek, Richard JT Wingate
    The development of brainstem auditory nuclei echoes the divergent evolutionary history of amniote auditory systems.

    Defining the location of promoter-associated R-loops at near-nucleotide resolution using bisDRIP-seq

    Jason G Dumelie, Samie R Jaffrey
    Genome-wide profiling of R-loops at near single-nucleotide resolution reveals distinct R-loop boundaries depending on the presence and location of the first exon-intron junction.

    Control of voluntary and optogenetically perturbed locomotion by spike rate and timing of neurons of the mouse cerebellar nuclei

    Rashmi Sarnaik, Indira M Raman
    Stride-related modulated firing by neurons of the cerebellar nuclei is required for smooth execution of practiced locomotion and persists more easily with synchronous than asynchronous Purkinje-mediated inhibition.

    Obligate coupling of CFTR pore opening to tight nucleotide-binding domain dimerization

    Csaba Mihályi et al.
    Coupling of CFTR pore opening to nucleotide binding domain dimerization does not depend on ATP binding, but is an inherent property of the channel protein and likely other ABC transporters.
