    Differing isoforms of the cobalamin binding photoreceptor AerR oppositely regulate photosystem expression

    Haruki Yamamoto, Mingxu Fang ... Carl E Bauer
    A novel B12 containing photoreceptor is synthesized as two different isoforms that interact with the same transcription factor, with one isoform directing activation and the other promoting repression of photosystem synthesis.

    Pathway-, layer- and cell-type-specific thalamic input to mouse barrel cortex

    B Semihcan Sermet, Pavel Truschow ... Carl CH Petersen
    Two distinct thalamocortical pathways were found to provide differential excitatory synaptic input to distinct cell-types across layers of mouse primary somatosensory barrel cortex.

    Live-cell single particle imaging reveals the role of RNA polymerase II in histone H2A.Z eviction

    Anand Ranjan, Vu Q Nguyen ... Carl Wu
    Histone variant H2A.Z is deposited near transcription start sites by the chromatin remodeler SWR1 and seems to be removed by RNA polymerase II at an early stage of transcription elongation.

    Missense mutations in CRX homeodomain cause dominant retinopathies through two distinct mechanisms

    Yiqiao Zheng, Chi Sun ... Shiming Chen
    The integrated analysis of multi-omics and functional evidence both in vitro and in knock-in mouse models reveal novel gain-of-function pathogenic mechanisms of dominant CRX HD missense mutations.

    A single-chain and fast-responding light-inducible Cre recombinase as a novel optogenetic switch

    Hélène Duplus-Bottin, Martin Spichty ... Gaël Yvert
    A single protein catalyzes site-specific DNA recombination upon blue-light illumination.

    ATP sensing in living plant cells reveals tissue gradients and stress dynamics of energy physiology

    Valentina De Col, Philippe Fuchs ... Markus Schwarzländer
    The monitoring of ATP dynamics in living plants using fluorescent protein biosensor provides evidence for the complex relationship between cellular energy status and growth.

    A role of OCRL in clathrin-coated pit dynamics and uncoating revealed by studies of Lowe syndrome cells

    Ramiro Nández, Daniel M Balkin ... Pietro De Camilli
    Studies of Lowe syndrome patient cells, which lack the inositol 5-phosphatase OCRL, suggest that a defect in endocytosis plays a role in the pathological manifestations of the disease.

    Architectural principles for Hfq/Crc-mediated regulation of gene expression

    Xue Yuan Pei, Tom Dendooven ... Ben F Luisi
    Structural insights show how RNA chaperones cooperate to recognise defined target transcripts and suppress gene expression.

    Activation of PTHrP-cAMP-CREB1 signaling following p53 loss is essential for osteosarcoma initiation and maintenance

    Mannu K Walia, Patricia MW Ho ... Carl R Walkley
    The loss of p53 in bone cells activates critical signaling pathways; these are also essential in bone cancer.
