    Agonist-mediated switching of ion selectivity in TPC2 differentially promotes lysosomal function

    Susanne Gerndt et al.
    The lysosomal ion channel TPC2 emerges as an example of an ion channel in which ion selectivity is not fixed but rather agonist-selective.

    Observation of long-range tertiary interactions during ligand binding by the TPP riboswitch aptamer

    Van K Duesterberg et al.
    The combined use of optical trapping and single-molecule FRET permits the study of riboswitch structure formation and conformational dynamics at the same time.

    Sweet neurons inhibit texture discrimination by signaling TMC-expressing mechanosensitive neurons in Drosophila

    Shun-Fan Wu et al.
    Drosophila use distinct sensory mechanisms to detect and integrate the same tactile and taste information in two decision-making tasks that serve two different purposes.

    Sumoylation promotes optimal APC/C activation and timely anaphase

    Christine C Lee et al.
    The Anaphase Promoting Complex/Cyclosome is regulated by sumoylation to ensure timely mitotic exit in human cells.

    The master cell cycle regulator APC-Cdc20 regulates ciliary length and disassembly of the primary cilium

    Weiping Wang et al.
    The anaphase promoting complex (APC) has an essential role in ubiquitin-mediated proteolysis in the disassembly of cilia.

    tec-1 kinase negatively regulates regenerative neurogenesis in planarians

    Alexander Karge et al.
    RNAi screening in planarians finds that inhibition of the TEC-family protein tyrosine kinase tec-1 increases the regeneration of neurons through enhancement of cell survival.

    Structural mechanisms of phospholipid activation of the human TPC2 channel

    Ji She et al.
    Cryo-EM structures of human TPC2 channel in the ligand-bound and apo states reveal the structural mechanism of PI(3,5)P2 lipid regulated gating of TPC2.

    A metabolic switch controls intestinal differentiation downstream of Adenomatous polyposis coli (APC)

    Imelda T Sandoval et al.
    The tumor suppressor APC regulates a metabolic program that drives normal intestinal differentiation in zebrafish.

    Precise regulation of the guidance receptor DMA-1 by KPC-1/Furin instructs dendritic branching decisions

    Xintong Dong et al.
    The enzyme KPC-1/Furin down-regulates the DMA-1 receptor in neurons, allowing growing dendrites to migrate away from intermediate targets.

    Ordered dephosphorylation initiated by the selective proteolysis of cyclin B drives mitotic exit

    James Holder et al.
    Selective APC/C-mediated proteolysis of cyclin B drives progression through the metaphase-anaphase transition whilst wide-spread waves of dephosphorylation co-ordinate the subsequent events of mitotic exit.
