General description

Synapsin-1 (UniProt P17599; also known as Synapsin I) is encoded by the SYN1 gene (Gene ID 281510) in bovine species. The synapins constitute a family of abundant neuronal phosphoproteins that regulate SV trafficking and neurotransmitter release at the pre-synaptic terminal. Three genes exisit in mammals, encoding altogether 11 synapsin members by alternative splicings (Synapsin Ia & Ib by SYN1, Synapsin IIa & IIb by SYN2, Synapsin IIIa through IIIf by SYN3), Syn III is the most precociously expressed isoform that has a role in the early phases of neural development and is downregulated in mature neurons. On the other hand, Syn I and Syn II are expressed at low levels at birth and their expressions progressively increase during synaptogenesis to reach a stable plateau at 1–2 months of life. The NH2-terminal region is divided into A, B, and C domains and is highly conserved among synapsin isoforms. Synapsins are regulated by postransloational phosphorylations. Domain A contains PKA and CaMKI/IV phosphorylation sites, domain B contains MAPK/Erk phosphorylation sites, and domain C is phosphorylated by Src. The C-terminal region contains spliced domains and diverge among synapsin isoforms (domain D in Syn Ia and Ib, domain G in Syn IIa and IIb, domain H in Syn IIa, and domain J in Syn IIIa), although they all bear proline-rich regions binding to several SH3-containing proteins and additional phosphorylation sites for CaMKII, MAPK/Erk, and cdk1/5.


Clone 10.22 reacts with both synapsin-1 spliced isoforms (Ia and Ib), but not synapsin-2 spliced isoform IIa or IIb (Vaccaro, P., et al. (1997). Brain Res. Mol. Brain Res. 52(1):1-16).


Epitope: Pro-rich domain D.

Purified bovine brain synapsin-1.


Immunohistochemistry Analysis: A 1:50 dilution from a representative lot detected Synapsin-1 in human, mouse, and rat cerebral cortex tissues.
Western Blotting Analysis: A representative lot detected synapsin Ia/Ib in mouse cortical neuron lysates (Medrihan, L., et al. (2013). Nat. Commun. 4:1512).
Western Blotting Analysis: A representative lot detected purified bovine brain synapsin Ia/Ib (Messa, M., et al. (2010). J. Cell Sci. 123(13):2256-2265).
Western Blotting Analysis: A representative lot detected synapsin-1 in Torpedo (electric ray) synaptosomal preparations and in GST-cyclophilin B pull-downs (Lane-Guermonprez, L., et al. (2005). J. Neurochem. 93(6):1401-1411).
Western Blotting Analysis: A representative lot detected synapsin-1 in the same rat brain subcellular fractions as cyclophilin B (Lane-Guermonprez, L., et al. (2005). J. Neurochem. 93(6):1401-1411).
Western Blotting Analysis: A representative lot detected synapsin Ia/Ib, but not IIa/IIb, in rat brain post-nuclear supernatants (Vaccaro, P., et al. (1997). Brain Res. Mol. Brain Res. 52(1):1-16).
Immunoprecipitation Analysis: A representative lot immunoprecipitated synapsin Ia/Ib, but not IIa/IIb, from rat brain synaptosomal preparations using protein G beads with pre-bound rabbit anti-mouse IgG (Vaccaro, P., et al. (1997). Brain Res. Mol. Brain Res. 52(1):1-16).
Immunofluorescence Analysis: Clone 10.22 ascites fluid was employed to localize synapsin-1 immunoreactivity within retinal inner plexiform layer (IPL) of floating or whole-mount rat retinas (Mandell, J.W., et al. (1992). J. Neurosci. 12(5):1736-1749).
Note: Clone 10.22 does not bind significantly to protein G. For immunoprecipitation application, pre-coat protein G beads with an anti-mouse IgG antibody is recommended (Vaccaro, P., et al. (1997). Brain Res. Mol. Brain Res. 52(1):1-16).
