Research Backgrounds

Function:

t-SNARE involved in the molecular regulation of neurotransmitter release. May play an important role in the synaptic function of specific neuronal systems. Associates with proteins involved in vesicle docking and membrane fusion. Regulates plasma membrane recycling through its interaction with CENPF. Modulates the gating characteristics of the delayed rectifier voltage-dependent potassium channel KCNB1 in pancreatic beta cells.

PTMs:

Palmitoylated. Cys-85 appears to be the main site, and palmitoylation is required for membrane association (By similarity).

(Microbial infection) Targeted and hydrolyzed by C.botulinum neurotoxin type A (BoNT/A, botA) which hydrolyzes the 197-Gln-|-Arg-198 bond and inhibits neurotransmitter release.

(Microbial infection) Targeted and hydrolyzed by C.botulinum neurotoxin type C (BoNT/C) which hydrolyzes the 198-Arg-|-Ala-199 bond and inhibits neurotransmitter release. C.botulinum type C only rarely infects humans.

(Microbial infection) Targeted and hydrolyzed by C.botulinum neurotoxin type E (BoNT/E) which hydrolyzes the 180-Arg-|-Ile-181 bond and inhibits neurotransmitter release.

Subcellular Location:

Cytoplasm>Perinuclear region. Cell membrane>Lipid-anchor. Cell junction>Synapse>Synaptosome. Photoreceptor inner segment.
Note: Membrane association requires palmitoylation. Expressed throughout cytoplasm, concentrating at the perinuclear region. Colocalizes with KCNB1 at the cell membrane (By similarity). Colocalizes with PLCL1 at the cell membrane (By similarity).

Tissue Specificity:

Neurons of the neocortex, hippocampus, piriform cortex, anterior thalamic nuclei, pontine nuclei, and granule cells of the cerebellum.

Subunit Structure:

Part of the SNARE core complex containing SNAP25, VAMP2 and STX1A; this complex binds CPLX1. Found in a complex containing SYT1, SV2B and syntaxin-1 (By similarity). Found in a ternary complex with STX1A and VAMP8 (By similarity). Interacts with HSC70 and with SYT9, forming a complex with DNAJC5 (By similarity). The interaction with SYT9 is inhibited in presence of calcium (By similarity). Isoform 1 and isoform 2 interact with BLOC1S6. Interacts with CENPF (By similarity). Interacts with EQTN (By similarity). Interacts with HGS (By similarity). Interacts with KCNB1 (via N-terminus); reduces the voltage-dependent potassium channel KCNB1 activity in pancreatic beta cells (By similarity). Interacts with OTOF (By similarity). Interacts with RIMS1 (By similarity). Interacts with SNAPIN (By similarity). Interacts with STXBP6 (By similarity). Interacts with TRIM9 (By similarity). Interacts with ZDHHC13 (via ANK repeats) (By similarity). Interacts with ZDHHC17 (via ANK repeats). Associates with the BLOC-1 complex. Interacts with PLCL1 (via C2 domain) (By similarity). Interacts with PRRT2; this interaction may impair the formation of the SNARE complex. Interacts with alpha-synuclein/SNCA. Interacts with PRPH2 (By similarity). Interacts with ROM1 (By similarity). Interacts with STX3 (By similarity).

Application: WB    Species: Rat    Sample: spinal cord tissues

Figure 7 Ser727 of STAT3 increased its interaction with PKCε. (a) Endogenous PKCε was immunoprecipitated from cell lysates, and immune complexes and total cell lysates were analyzed by Western blot analysis with PKCε and STAT3 antibodies. Endogenous immune PKCε/STAT3 complexes were detected in the rat spinal cord tissues. (b) IL-6 promoter-firefly luciferase reporter plasmid (0.5 μg), PKCε (1 μg), and STAT3 (1 μg) were cotransfected overnight into HEK293 cells. The transfected cells were incubated with 1 μg/mL lipopolysaccharide (LPS) for 12 h. Interleukin-6 promoter activity increased by STAT3 was further enhanced by PKCε and STAT3, indicating that PKCε improved the ability of STAT3 to bind to IL-6 promoter. Data are shown as means ± SD (n = 6). ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001; one-way ANOVA followed by Bonferroni tests. (c, d) HKE293 cells were transfected with GFP, GFP-PKCε, Flag, Flag-STAT3, and phosphomimetic and dephosphomimetic mutants of STAT3, and then, immunoprecipitants were assayed. Protein complexes were detected using an anti-GFP antibody (c), and then, relative PKCε binding to STAT3 was quantified (d). Data are presented as means ± SD (n = 3). ∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001; one-way ANOVA followed by Bonferroni tests.

Application: WB    Species: Mice    Sample: brain tissue

FIGURE 5 Ubiquitin and synaptic protein expression changed in isoflurane-exposed aged mice. (A) Ubiquitin expression was decreased in the cortex brain tissue in the ISO-15 group, while there was no significant difference in synaptic protein SNAP25 expression in the cortex (n = 6, *p < 0.05). (B) In the brain tissue of cortex, there was no significant difference in the expression level of synapsin I and the phosphorylation level of synapsin I S9 and S605 between CON group, ISO-12.5 group, and ISO-15 group. In the brain tissue of the hippocampus, the expression level of synapsin I and the phosphorylation level of synapsin I S9 and S605 were decreased in both the ISO-12.5 group and ISO-15 group, compared with the CON group, and the expression level of CHIP had a dramatic decline in the ISO-15 group (n = 6, *p < 0.05).

Application: WB    Species: mouse    Sample: N2a cells
