    Structures reveal opening of the store-operated calcium channel Orai

    Xiaowei Hou et al.
    The structure of the calcium channel Orai in an open conformation reveals a dilated pore and gives insight into mechanisms of ion permeation and calcium selectivity.

    Neurosecretory protein GL stimulates food intake, de novo lipogenesis, and onset of obesity

    Eiko Iwakoshi-Ukena et al.
    Neurosecretory protein GL, a previously unknown mammalian neuropeptide, is a novel hypothalamic factor which regulates feeding behavior and peripheral lipogenesis in animals.

    The deca-GX3 proteins Yae1-Lto1 function as adaptors recruiting the ABC protein Rli1 for iron-sulfur cluster insertion

    Viktoria Désirée Paul et al.
    Two newly identified assembly factors for the ribosome-associated iron-sulfur protein Rli1 reveal a general mechanism for how the cytosolic iron-sulfur protein assembly (CIA) machinery recruits apoproteins.

    Quantitative H2S-mediated protein sulfhydration reveals metabolic reprogramming during the integrated stress response

    Xing-Huang Gao et al.
    ATF4, the master regulator of transcription during the Integrated Stress Response (ISR), causes global changes in cysteine sulfhydration of proteins and this event causes cellular metabolic reprogramming.

    A chloroplast retrograde signal, 3’-phosphoadenosine 5’-phosphate, acts as a secondary messenger in abscisic acid signaling in stomatal closure and germination

    Wannarat Pornsiriwong et al.
    Molecular signals from chloroplasts can synergistically interact with the plant hormone, abscisic acid (ABA), to regulate non-canonical signaling pathways mediating fundamental cellular processes including stomatal closure, seed dormancy and germination.

    Expression of SREBP-1c Requires SREBP-2-mediated Generation of a Sterol Ligand for LXR in Livers of Mice

    Shunxing Rong et al.
    SREBP-2 directly regulates genes involved in cholesterol homeostasis and indirectly regulates fatty acid synthesis through the production of a ligand responsible for the activation of LXR and SREBP-1c.

    B cell activation involves nanoscale receptor reorganizations and inside-out signaling by Syk

    Kathrin Kläsener et al.
    Studying the earliest events in B cell activation reveals that the B cell antigen receptor is opened and activated via the phosphorylation and binding by the spleen tyrosine kinase (Syk).

    SIR-2.1 integrates metabolic homeostasis with the reproductive neuromuscular excitability in early aging male Caenorhabditis elegans

    Xiaoyan Guo, L René García
    A protein called SIR-2.1 helps to protect worms from the effects of aging by regulating metabolic processes that would otherwise generate damaging reactive oxygen species.

    In vivo proteomic mapping through GFP-directed proximity-dependent biotin labelling in zebrafish

    Zherui Xiong et al.
    BLITZ system enables proximity-dependent biotin labelling in live zebrafish embryos with cell and tissue specificity, providing a versatile and valuable tool for proteomic discovery using the zebrafish model.

    Human DECR1 is an androgen-repressed survival factor that regulates PUFA oxidation to protect prostate tumor cells from ferroptosis

    Zeyad D Nassar et al.
    DECR1, a rate-limiting enzyme for polyunsaturated fatty acid (PUFA) β-oxidation, is an androgen-repressed gene in prostate cancer cells that limits oxidative stress to promote cancer cell survival.
