text
  • fusion of synaptic vesicles to target membranes
  • VAMP1 and VAMP2, both co-sediment and co-localize with NPPA
  • basic FUNCTION
  • soluble N ethylmaleimide-sensitive factor-attachment protein receptor, SNARE protein
  • calcium-dependent role in the docking and fusion of synaptic vesicles with the presynaptic membrane
  • playing a central role in neural exocytosis
  • its cleavage modifies the coupling between channels and release-competent vesicles
  • potentially having a vital role in a subset of central nervous system tissues
  • its structure is clearly controlled by protein-lipid interactions
  • with VAMP2, and syntaxin-4 regulate NPPA release from cardiac myocyte
  • with other VAMPs, has differential membrane fusion capacities, and imply that with the exception of VAMP5, VAMPs are essentially redundant in mediating fusion with plasma membrane t-SNAREs
  • dual role of VAMP1, SNAP25, STX1A in exo- and endocytosis suggests that SNARE proteins may be molecular substrates contributing to the exocytosis-endocytosis coupling, which maintains exocytosis in secretory cells
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS exocytosis transport
    PATHWAY
    metabolism
    signaling neurotransmission
    a component
  • constituent of a synaptic core complex with syntaxin and synaptosome associated proteins (SNAP25)
  • three SNAREs, STX4, VAMP1 and VAMP2, form a SNARE complex inside cardiac myocytes
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • binding to t-SNARES, syntaxin (STX) and SNAP25 after the fusion of synaptic vesicles to plasma membrane
  • interacting with VAPA and VAPB
  • interacting with BCAP29
  • dual role of SNAP25 and VAMP1 in both exocytosis and slow endocytosis at conventional synapses
