  • 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.
  • Tissue specificity
    Neurons of the neocortex, hippocampus, piriform cortex, anterior thalamic nuclei, pontine nuclei, and granule cells of the cerebellum.
  • Sequence similarities
    Belongs to the SNAP-25 family.
    Contains 2 t-SNARE coiled-coil homology domains.
  • Post-translational
    Palmitoylated. Cys-85 appears to be the main site, and palmitoylation is required for membrane association.
  • Cellular localization
    Cytoplasm > perinuclear region. Cell membrane. Cell junction > synapse > synaptosome. Membrane association requires palmitoylation. Expressed throughout cytoplasm, concentrating at the perinuclear region.

  • SNAP25 was immunoprecipitated using 0.5mg Rat Spinal Cord tissue lysate, 5µg of Rabbit polyclonal to SNAP25 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, Rat Spinal Cord tissue lysate lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab41726.
    Secondary: Clean-Blot IP Detection Reagent (HRP) at 1/500 dilution.
    Band: 26kDa; SNAP25; non specific bands - 55 and 98kDa: We are unsure as to the identity of this extra band.

I'm working on a project that involves developing a procedure to map epitopes using mass spec. To do this we are using different types of anitbodies specific to SNAP25. The SNAP25 we are using is Genway,human recombinant SNAP25 made in E. coli. Here is a link to the protein and all of the specifications: http://www.genwaybio.com/product_info.php?products_id=46229 I have already mapped a couple of epitopes including abcam's 66066. What I am looking for is a anti-SNAP25 antibody that has an epitope in a region of SNAP25 that we have had success in dectecting with the mass spec. These areas include: -(43)MQRRADQ LADESLESTR RMLQLVEESK DAGIRTLVML DEQGEQLERI EEGMDQINK(98)- -(150)VDEREQMAIS GGFI(163)- -(170)ARENEMDENL EQVSGIIGNL RHMALDMGNE IDTQNRQIDR IME(203)- Also I have already used an antibody with the epitope of -(214)ANQRATKMLGSG(226)- so I would not be interested in another antibody in the same region. In conclusion I am looking for an anti-SNAP25 anitbody who's epitope is somewhere in the region(s) above. If you do find an antibody it would be helpful if you could include the sequence of the epitope. It is important to the experiment to know the exact sequence. I really hope this email is not too confusing. Also this is my second time writing, the first time I got an email back with specific questions but I could not reply back to the person trying to help me. Not sure what the problem was, but I think I have included all the info you may need. Thanks for your help, have a good day.

Thank you for providing the additional information. I see your earlier e-mail in our records. We have 15 SNAP25 antibodies in our catalogue. Some are polyclonals raised against full-length SNAP25, and since these will potentially recognize multiple epitopes along the entire protein, they will not be useful for your project. Similarly, some others are monoclonal antibodies raised against the full-length protein but the single epitope they recognize has not been mapped to a specific range of amino acids. Of the remaining antibodies, several are raised agains the C-terminus which you already have an antibody against. One exception: Antibody ab41726 is raised agianst a peptide (amino acids ASQPARVVDEREQMA)which has some overlap with a region you specified: (150)VDEREQMAISGGFI(163) However, the antibody may recognize an epitope composed of amino acids outside the range: ASQPARV. There are several other antibodies which may be sueful but I need to obtain the immunogen sequences from the laboratories that produce them: ab53723 ab109105 ab68859 ab72396 ab68858 ab72394 I will forward the information when I receive it. Hopefully one or more of these will meet your needs.
