    A novel region in the CaV2.1 α1 subunit C-terminus regulates fast synaptic vesicle fusion and vesicle docking at the mammalian presynaptic active zone

    Matthias Lübbert et al.
    A novel region in the CaV2.1 α1 subunit regulates coupling of synaptic vesicles to CaV2.1 calcium channels, synaptic vesicle release and docking, and the size of the fast and total releasable pools of synaptic vesicles.

    Sec17/Sec18 act twice, enhancing membrane fusion and then disassembling cis-SNARE complexes

    Hongki Song et al.
    Sec17 (αSNAP) and Sec18 (NSF) are shown to act twice, to promote fusion per se and to recycle SNAREs after fusion.

    Distinct regulation of dopamine D2S and D2L autoreceptor signaling by calcium

    Stephanie C Gantz et al.
    The loss of calcium-dependent D2 autoreceptor desensitization caused by prior in vivo cocaine exposure may be conferred by an unexpected role of the D2L splice variant as an autoreceptor.

    Membranes linked by trans-SNARE complexes require lipids prone to non-bilayer structure for progression to fusion

    Michael Zick et al.
    Lipids with a propensity to form nonbilayer structures must be present for the last step of membrane fusion to take place.

    Position of UNC-13 in the active zone regulates synaptic vesicle release probability and release kinetics

    Keming Zhou et al.
    The precise position of UNC-13 at the active zone near a synapse depends on the N-terminus of the protein, and the C2A domain in particular, and is essential for accelerating neurotransmitter release.

    IP3 mediated global Ca2+ signals arise through two temporally and spatially distinct modes of Ca2+ release

    Jeffrey T Lock, Ian Parker
    Cell-wide Ca2+ signals that regulate numerous cellular functions comprise dual Ca2+ release modes through IP3 receptors, punctate transients mediated by clustered receptors and spatiotemporally diffuse release through functionally distinct receptors.

    Microglial calcium signaling is attuned to neuronal activity in awake mice

    Anthony D Umpierre et al.
    Microglial processes engage calcium signaling in response to hyper- or hypo-active shifts in neuronal activity.

    Conformational change within the extracellular domain of B cell receptor in B cell activation upon antigen binding

    Zhixun Shen et al.
    Conformational changes occur within extracellular domain of BCR upon antigen engagement, and these conformational changes are related with the strength of BCR activation and are distinct in IgM- and IgG-BCR.

    Structural basis of Ca2+-dependent activation and lipid transport by a TMEM16 scramblase

    Maria E Falzone et al.
    Structures of a TMEM16 phospholipid scramblase reveal that its Ca2+-dependent activation entails global conformational changes and how these rearrangements affect the membrane to enable transbilayer lipid transfer.

    Distinct ‘safe zones’ at the nuclear envelope ensure robust replication of heterochromatic chromosome regions

    Hani Ebrahimi et al.
    The nuclear periphery houses compositionally and functionally distinct domains, one of which provides a 'safe zone' for replication and reassembly of heterochromatic genome regions.
