    EFHC1, implicated in juvenile myoclonic epilepsy, functions at the cilium and synapse to modulate dopamine signaling

    Catrina M Loucks, Kwangjin Park ... Michel R Leroux
    C. elegans EFHC1 influences neuronal transmission through the cilium and the synapse.

    Nanobody-directed targeting of optogenetic tools to study signaling in the primary cilium

    Jan N Hansen, Fabian Kaiser ... Dagmar Wachten
    Trafficking of optogenetic tools to primary cilia using nanobodies allows to study cAMP signaling with spatial and temporal resolution independent of the cell body.

    Atypical calcium regulation of the PKD2-L1 polycystin ion channel

    Paul G DeCaen, Xiaowen Liu ... David E Clapham
    Outward calcium ion currents desensitize the human PKD2-L1 ion channel via a mechanism that is independent of cytosolic motifs.

    A WDR35-dependent coat protein complex transports ciliary membrane cargo vesicles to cilia

    Tooba Quidwai, Jiaolong Wang ... Pleasantine Mill
    Electron tomography and biochemical approaches demonstrate a direct role for WDR35, beyond integrity of the IFT-A holocomplex, in the formation and fusion of electron-dense-coated vesicles to the ciliary sheath and pocket for delivery of cargos necessary for axoneme elongation.

    Ion channels and calcium signaling in motile cilia

    Julia F Doerner, Markus Delling, David E Clapham
    Direct patch clamp of ependymal motile cilia reveals that voltage-gated calcium channels in the cell body dominate their electrical and calcium signaling properties.

    Structural mechanism of ligand activation in human calcium-sensing receptor

    Yong Geng, Lidia Mosyak ... Qing R Fan
    L-amino acids are agonists of calcium-sensing receptor, and act jointly with calcium and phosphate ions to control receptor function.

    Calcium dynamics regulating the timing of decision-making in C. elegans

    Yuki Tanimoto, Akiko Yamazoe-Umemoto ... Koutarou D Kimura
    A series of quantitative behavioural and opto-physiological analyses using a novel robot microscope system reveals that C. elegans computes the time-differential and time-integral of sensory information for decision-making during olfactory navigation.

    Structural determinants of voltage-gating properties in calcium channels

    Monica L Fernández-Quintero, Yousra El Ghaleb ... Bernhard E Flucher
    Structure modeling, site-directed mutagenesis, and current recordings revealed the mechanism by which stabilization of voltage sensors in the resting and activated states determines the gating properties of the CaV1.1 calcium channel.

    Calcium-mediated shaping of naive CD4 T-cell phenotype and function

    Vincent Guichard, Nelly Bonilla ... Cédric Auffray
    Calcium-calcineurin signaling cascade drives the acquisition of both the phenotype of the most self-reactive naive CD4 T cells and their enhanced cell-intrinsic ability to commit into induced regulatory T cells upon activation.

    Pathogenic LRRK2 control of primary cilia and Hedgehog signaling in neurons and astrocytes of mouse brain

    Shahzad S Khan, Yuriko Sobu ... Suzanne R Pfeffer
    Striatal cholinergic interneurons and astrocytes lose cilia and show dysregulation of Hedgehog signaling in mice with a Parkinson's disease-associated, G2019S LRRK2 mutation or upon loss of PPM1H phosphatase specific for LRRK2-phosphorylated Rab GTPases.
