| Background Information | Synaptophysin (UniProt P20488; also known as Major synaptic vesicle protein p38) is encoded by the SYP gene (Gene ID 280937) in bovine species. Synaptophysin is a 38 kDa four-transmembrane glycoprotein on synaptic vesicle (SV) with both its N- and C-termini exposed cytoplasmically. Synaptophysin forms homomultimers in the SV membrane and is heavily phosphorylated on tyrosine residues in its C-terminal pentapeptide repeats. Synapthophysin is also known to interact with SV v-SNARE protein synaptobrevin II (sybII) when sybII is not engaged with other SNARE proteins, suggesting a role of synaptophysin in sybII retrieval during SV endocytosis. Consistently, synaptophysin-knockout neurons display reduced level of sybII at their nerve terminals. |

| Key Applications |
|
| Application Notes | Immunohistochemistry Analysis: A 1:50 dilution from a representative lot detected Synaptophysin in human cerebellum and cerebral cortex tissue sections. Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected Synaptophysin in 10 µg of rat hippocampus and human whole brain tissue lysates. Immunocytochemistry Analysis: Representative lots immunostained presynaptic vesicles of 4% formaldehyde-fxied, 0.2% Triton X-100-permeabilzied primary mouse hippocampal neurons by fluorescent immunocytochemistry (Hu, X., et al. (2008). J. Neurosci. 28(49):13094-13105; Tarr, P.T., and Edwards, P.A. (2008). J. Lipid Res. 49(1):169-182). Immunofluorescence Analysis: A representative lot immunostained presynaptic membrane of neurons by fluorescent immunohistochemistry staining of 4% paraformaldehyde-fixed, 0.3% Triton X-100-permeabilized, OCT-embedded rat spinal cord cryosections (Stück, E.D., et al. (2012). Neural Plast. 2012:261345). Immunofluorescence Analysis: A representative lot immunostained synaptophysin around a large neuron in the ventral horn of the lumbar (L3/L4) segment by fluorescent immunohistochemistry staining of 2% paraformaldehyde/0.2% parabenzoquinone-fixed free-floating rat spinal cord sections (Macias, M., et al. (2009). BMC Neurosci. 10:144). Immunofluorescence Analysis: A representative lot immunostained synaptophysin in bovine (pancreas) and human (pancreas, pheochromocytoma, and islet-cell carcinoma) frozen tissue sections (Wiedenmann, B., et al. (1986). Proc. Natl. Acad. Sci. U.S.A. 83(10):3500-3504). Western Blotting Analysis: A representative lot detected an upregulated synaptophysin expression in human iPSCs with a 4-bp deletion in DISC1 gene (Wen, Z., et al. (2014). Nature. 515(7527):414-418). Western Blotting Analysis: A representative lot detected synaptophysin distribution among PC12 rat pheochromocytoma cell membrane fractions (Salazar, G., et al. (2005). Mol. Biol. Cell. 16(8):3692-3704). Western Blotting Analysis: A representative lot detected only synaptophysin recombinant contructs that contained the flexible segment -SGGGG- in the center of the c-terminal pentapeptide repeats (Knaus, P., and Betz, H. (1990). FEBS Lett. 261(2):358-360). |
