    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.

    Membrane fluidity is regulated by the C. elegans transmembrane protein FLD-1 and its human homologs TLCD1/2

    Mario Ruiz et al.
    Inhibition of C. elegans FLD-1 or Human TLCD1/2 prevents saturated fat lipotoxicity by allowing increased levels of membrane phospholipids that contain fluidizing long-chain polyunsaturated fatty acids.

    The phage L capsid decoration protein has a novel OB-fold and an unusual capsid binding strategy

    Rebecca L Newcomer et al.
    The structure of phage L's Dec demonstrates a new fold within this family of proteins, and shows modulation of capsid binding occurs through two sites, with site 1 being preferred.

    A new topology of the HK97-like fold revealed in Bordetella bacteriophage by cryoEM at 3.5 Å resolution

    Xing Zhang et al.
    Cryo electron microscopy and structure-based mutagenesis reveal that the bacteriophage BPP-1 contains two of the three major recognized viral folds, one of which exhibits a new topology.

    The Melanocortin Receptor Accessory Protein 2 promotes food intake through inhibition of the Prokineticin Receptor-1

    Anna L Chaly et al.
    A non-melanocortin G-protein coupled receptor is inhibited by the Melanocortin Receptor Accessory Protein 2 (MRAP2) to control food intake in mammals.

    Nitric oxide radicals are emitted by wasp eggs to kill mold fungi

    Erhard Strohm et al.
    To protect their food and themselves against detrimental mould fungi, the eggs of a wasp species synthesize and emit remarkable amounts of gaseous nitrogen oxides that are highly effective antimicrobials.

    Origin of a folded repeat protein from an intrinsically disordered ancestor

    Hongbo Zhu et al.
    Minimal changes allow an ancestral, unfolded peptide to adopt a known fold by repetition, illuminating a possible path for the emergence of folded proteins at the origin of life.

    An effector of the Irish potato famine pathogen antagonizes a host autophagy cargo receptor

    Yasin F Dagdas et al.
    A plant pathogen effector evolved a short linear motif to subvert autophagic defenses by antagonising a host cargo receptor.

    Lipoate-binding proteins and specific lipoate-protein ligases in microbial sulfur oxidation reveal an atpyical role for an old cofactor

    Xinyun Cao et al.
    An unexpected new biological function was discovered for the universally conserved cofactor lipoate, as lipoate-binding proteins proved essential for a novel wide-spread prokaryotic sulfur oxidation pathway.

    Multimodal cell tracking from systemic administration to tumour growth by combining gold nanorods and reporter genes

    Joan Comenge et al.
    Combined cell labelling with a bi-cistronic reporter-gene vector and gold nanorods enables short- and long-term cell tracking in vivo via multimodal imaging (multispectral optoacoustic tomography, bioluminescence, fluorescence) with high spatial resolution.
