靶點詳情

  • 功能：
    Ca(2+) sensor involved in Ca(2+)-dependent exocytosis of secretory and synaptic vesicles through Ca(2+) and phospholipid binding to the C2 domain. Ca(2+) induces binding of the C2-domains to phospholipid membranes and to assembled SNARE-complexes; both actions contribute to triggering exocytosis. SYT7 binds Ca(2+) with high affinity and slow kinetics compared to other synaptotagmins. Involved in Ca(2+)-triggered lysosomal exocytosis, a major component of the plasma membrane repair. Ca(2+)-regulated delivery of lysosomal membranes to the cell surface is also involved in the phagocytic uptake of particles by macrophages. Ca(2+)-triggered lysosomal exocytosis also plays a role in bone remodeling by regulating secretory pathways in osteoclasts and osteoblasts. Involved in cholesterol transport from lysosome to peroxisome by promoting membrane contacts between lysosomes and peroxisomes: probably acts by promoting vesicle fusion by binding phosphatidylinositol-4,5-bisphosphate on peroxisomal membranes. Acts as a key mediator of synaptic facilitation, a process also named short-term synaptic potentiation: synaptic facilitation takes place at synapses with a low initial release probability and is caused by influx of Ca(2+) into the axon terminal after spike generation, increasing the release probability of neurotransmitters. Probably mediates synaptic facilitation by directly increasing the probability of release. May also contribute to synaptic facilitation by regulating synaptic vesicle replenishment, a process required to ensure that synaptic vesicles are ready for the arrival of the next action potential: SYT7 is required for synaptic vesicle replenishment by acting as a sensor for Ca(2+) and by forming a complex with calmodulin. Also acts as a regulator of Ca(2+)-dependent insulin and glucagon secretion in beta-cells. Triggers exocytosis by promoting fusion pore opening and fusion pore expansion in chromaffin cells. Also regulates the secretion of some non-synaptic secretory granules of specialized cells.

    1. identify a distinct function of Syt7 ensuring the efficiency of high-frequency inhibitory synaptic transmission PMID: 29166601
    2. data demonstrate the previously unrecognized observation that PLXNC1 deficiency permits Syt7-mediated macrophage migration and enhances mammalian lung fibrosis PMID: 27609773
    3. At the calyx synapse that syt7-dependent asynchronous release indeed does not produce a prolonged synaptic signal after a stimulus train and does not contribute to short-term plasticity, but induces a steady-state, asynchronous postsynaptic current during stimulus trains. This steady-state postsynaptic current sustains reliable generation of postsynaptic spikes that are precisely time locked to presynaptic spikes. PMID: 28521135
    4. synaptotagmin 7 (Syt7) is a calcium sensor that is required for facilitation at several central synapses PMID: 26738595
    5. Complex of syt 7 and calmodulin serves as a key regulator of synaptic vesicle replenishment in presynaptic nerve terminals. PMID: 24569478
    6. synaptotagmin-7 is directly activated by GLP-1 signaling and may serve as a drug target for boosting insulin secretion. PMID: 26216970
    7. knock-out of synaptotagmin-7 selectively impaired delayed asynchronous neurotransmitter release but not synchronous release. In contrast, the readily releasable vesicles after depletion recover normally in knock-out mice. PMID: 26245964
    8. Results demonstrate that synaptotagmin-7 functions as a positive regulator of GLP-1 secretion in intestinal L-cells and GLUTag cells, consistent with its proposed role as a calcium sensor in GLP-1 secretion. PMID: 21424898
    9. In synaptotagmin-7 KO mice defective insulin secretion and reduced insulin sensitivity were not sufficient to cause hyperglycaemia in the absence of enhanced glucagon secretion PMID: 20978738
    10. Mutations in Syt VII palmitoylation sites block trafficking of Syt VII, but not CD63, to lysosomes and phagosomes, whereas tyrosine replacement in the lysosomal targeting motif of CD63 causes both proteins to accumulate on the plasma membrane. PMID: 21041449
    11. synaptotagmin-7 controls fusion pore dynamics during exocytosis via a push-and-pull mechanism PMID: 20956309
    12. identified the conserved alternative splicing events in the spacer domain of Syt VII; also shown that Syt VIIa-GFP is mainly localized in the perinuclear region and tips of neurites (dense-core vesicles), and not in the plasma membrane PMID: 12071850
    13. the lysosomal synaptotagmin Syt VII is required for a mechanism that promotes phagolysosomal fusion and limits the intracellular growth of pathogenic bacteria PMID: 15178804
    14. Syt VII does not function as the calcium-dependent trigger for lysosomal exocytosis, but instead, restricts the kinetics and extent of calcium-dependent lysosomal fusion PMID: 15226824
    15. Syt VII regulates the Ca2+-dependent mobilization of lysosomes as a supplemental source of membrane during phagocytosis. PMID: 16982801
    16. Syt VII regulates perforin-mediated cytolytic CTL responses. PMID: 17237398
    17. These results show that Ca(2+) binding to the synaptotagmin-7 C(2) domains is physiologically important for stabilizing synaptotagmin-7 and that Ca(2+) binding by synaptotagmin-7 likely does not regulate synaptic vesicle exocytosis. PMID: 18308933
    18. These findings show that synaptotagmin-7 functions as a positive regulator of insulin secretion and may serve as a calcium sensor controlling insulin secretion in pancreatic beta cells. PMID: 18308938
    19. Syt7 regulates bone remodeling by modulating osteoclast and osteoblast secretion. PMID: 18539119
    20. Synaptotagmin-7 is a principal Ca(2+) sensor for glucagon secretion by pancreatic alpha cells. PMID: 19171650
