    Fusion surface structure, function, and dynamics of gamete fusogen HAP2

    Juan Feng et al.
    Structure, dynamics, and mutation of a gamete fusion protein and comparisons to viral homologues suggest that after trimerization the domain bearing the membrane-inserting fusion loops can pivot with respect to the trimer 3-fold axis.

    Crystal structure of intraflagellar transport protein 80 reveals a homo-dimer required for ciliogenesis

    Michael Taschner et al.
    CRISPR/Cas knockout of intraflagellar transport protein 80 shows that this subunit is absolutely required for ciliogenesis, and biophysical studies reveal that this protein may dimerize the intraflagellar transport complex.

    A G-protein activation cascade from Arl13B to Arl3 and implications for ciliary targeting of lipidated proteins

    Katja Gotthardt et al.
    The ciliary G-protein Arl13B – which is often mutated in Joubert syndrome – is the Guanine nucleotide exchange factor for the G-protein Arl3 and exclusively localizes to cilia.

    A new class of cyclin dependent kinase in Chlamydomonas is required for coupling cell size to cell division

    Yubing Li et al.
    CDKG1 is a D-cyclin dependent retinoblastoma related protein kinase whose abundance scales with cell size and controls cell division cycle number during multiple fission.

    Uni-directional ciliary membrane protein trafficking by a cytoplasmic retrograde IFT motor and ciliary ectosome shedding

    Muqing Cao et al.
    During cilium-generated signaling, ciliary membrane protein trafficking is unidirectional and ciliary membrane protein composition is regulated through action in the cytoplasm of the retrograde intraflagelllar transport (IFT) motor and shedding of ciliary ectosomes.

    Chloroplast acquisition without the gene transfer in kleptoplastic sea slugs, Plakobranchus ocellatus

    Taro Maeda et al.
    The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.

    A bioactive peptide amidating enzyme is required for ciliogenesis

    Dhivya Kumar et al.
    Analysis of Chlamydomonas, planaria and mice reveals a novel and unanticipated role for a peptide amidating enzyme in primary and motile ciliary assembly through effects on post-Golgi trafficking.

    Photosynthetic sea slugs induce protective changes to the light reactions of the chloroplasts they steal from algae

    Vesa Havurinne, Esa Tyystjärvi
    Slug chloroplasts avoid damage to photosynthesis by maintaining an oxidized electron transfer chain with the help of oxygen-sensitive electron acceptors.

    Cryo electron tomography with volta phase plate reveals novel structural foundations of the 96-nm axonemal repeat in the pathogen Trypanosoma brucei

    Simon Imhof et al.
    Cryo electron tomography provides the first high-resolution 3D axoneme structure from any pathogenic organism, revealing novel structures that support the unique motility of these pathogens through host tissues.
