findings reveal a novel signalling pathway involved in development of the semicircular canal system, and suggest a previously unrecognized role for NCS-1 in mitochondrial function via its association with several mitochondrial proteins.
Syb2 mutants harboring tryptophan at 4 different sites in the transmembrane domain reduced the rate-of-rise of mEPSCs in cultured hippocampal neurons. A computer simulation could account for this by slowing the flux of glutamate through synaptic fusion pores.The sites in synaptobrevin that influence this flux are identical to those shown previously to influence Ca(2+)-triggered exocytosis through endocrine fusion pores.
These observations provide evidence that the synaptobrevin-2 transmembrane domain catalyzes the membrane fusion process by its structural flexibility, actively setting the pace of fusion pore expansion.
Syp1 clears Syb2 from the presynaptic active zone to prevent short-term depression.
The balance between synaptophysin and sybII levels is critical for the correct targeting of sybII to synaptic vesicles and suggests that alterations in synaptophysin levels might affect the localisation of sybII and subsequent presynaptic performance.
Thus, lipid-anchored syb2 provides little or no support for exocytosis, and anchoring syb2 to a membrane by a TMD greatly improves its function
Vamp2 mutations impair the ability of Munc18-1 to promote trans-SNARE zippering. These mutations inhibit spontaneous as well as evoked neurotransmitter release, providing evidence for the Vamp2-regulating function of Munc18-1 in synaptic exocytosis.

synaptobrevin2 is expressed in cytotoxic T lymphocytes and exclusively localized on granzyme B-containing lytic granules.
Data suggest that tryptophans W89/W90 in juxtamembrane region/transmembrane domain of Syb2 act as fusion clamp in chromaffin cells; in mutant protein, alanines A89/A90 promote spontaneous membrane fusion.
The tryptophan moiety in SybII keeps secretory vesicles in the release-ready state and support a model wherein tryptophan-mediated protein-lipid interactions assist in bridging the apposing membranes before fusion.
microelectrode array measurements in specific hippocampal subregions of VAMP2(+/-) mice showed significant reductions in potassium-evoked glutamate release
VAMP2 and VAMP3 are expressed in JG cells, but only VAMP2 is targeted to renin-containing granules and mediates the stimulatory effect of cAMP on renin exocytosis.
To investigate the possible roles of selected synaptic and presynaptic membrane protein genetic polymorphisms (VAMP2, SNAP-25, synaptotagmin, and syntaxin 1A) in patients with multiple sclerosis
these findings implicate VAMP2 as the main VAMP isoform functionally involved in antibody secretion.
miR-185 inhibited osteosarcoma (OS) cell proliferation, migration and invasion. VAMP2 was validated as a direct target of miR-185. Study in human OS tissues confirm that decreased expression of miR-185 might be regarded as a tumor marker for the early diagnosis of OS, by manipulating of its interactive factors with VAMP2, to provide an effective novel therapeutic target for treatment of the OS tumor.
these results indicate that the activation of beta-ARs induces secretory granules and cell membrane fusion via the interaction of VAMP-2 and syntaxin-4 in a PKA- and F-actin-dependent manner in human submandibular gland. Up-regulated beta-ARs might participate in altering protein secretion in transplanted submandibular gland by promoting the interaction of VAMP-2 with syntaxin-4.
miR-493-5p overexpression promotes cell apoptosis and inhibits the proliferation and migration of liver cancer cells by negatively regulating the expression of VAMP.
Data suggest that A-syn (alpha-synuclein) promotes SNARE-dependent vesicle docking; phosphatidylserine (PS) removal from t-SNARE-bearing vesicles causes A-syn to inhibit vesicle docking; PS removal from v-SNARE-bearing vesicles promotes vesicle docking; the C-terminal 45 residues of A-syn are required for promotion of vesicle docking. (Here, t-SNARE is SNAP-25; v-SNARE is VAMP2.)

Lengthening juxtamembrane region of synaptobrevin-2 severely reduced occurrence of rapid single events, leaving slow ones unchanged. It also impaired increase in fast-fusion mode that normally follows elevation of intracellular Ca2+ levels.
The protein encoded by this gene is a member of the vesicle-associated membrane protein (VAMP)/synaptobrevin family. Synaptobrevins/VAMPs, syntaxins, and the 25-kD synaptosomal-associated protein SNAP25 are the main components of a protein complex involved in the docking and/or fusion of synaptic vesicles with the presynaptic membrane. This gene is thought to participate in neurotransmitter release at a step between docking and fusion. The protein forms a stable complex with syntaxin, synaptosomal-associated protein, 25 kD, and synaptotagmin. It also forms a distinct complex with synaptophysin. It is a likely candidate gene for familial infantile myasthenia (FIMG) because of its map location and because it encodes a synaptic vesicle protein of the type that has been implicated in the pathogenesis of FIMG.
