    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.

    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.

    The heteromeric PC-1/PC-2 polycystin complex is activated by the PC-1 N-terminus

    Kotdaji Ha et al.
    Soluble fragments cleaved from the N-terminus of PC-1 activate the PC-1/PC-2 heteromeric polycystin channel, describing for the first time that the N-terminus itself is an endogenous ligand.

    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.

    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.

    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.

    Selecting the most appropriate time points to profile in high-throughput studies

    Michael Kleyman et al.
    The Time Point Selection (or TPS) method is a general protocol for determining sampling rates for high throughout time series biological studies, that is efficient, cheap, scalable and works well for several different types of molecular data.

    The COMA complex interacts with Cse4 and positions Sli15/Ipl1 at the budding yeast inner kinetochore

    Josef Fischböck-Halwachs et al.
    The chromosomal passenger complex interacts with the inner kinetochore COMA complex through the Ctf19 C-terminus in vitro which is shown to be important for mediating accurate chromosome segregation.

    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.
