Descripción

General description

Synapsin-2 (UniProt Q63537; also known as Synapsin II) is encoded by the Syn2 gene (Gene ID 29179) in rat 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 in 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 regions contain 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.

Specificity

Clone 19.4 reacts with both synapsin-2 spliced isoforms (IIa and IIb). Clone 19.4 does not react with any of the two synapsin-1 spliced isoforms (Vaccaro, P., et al. (1997). Brain Res. Mol. Brain Res. 52(1):1-16).

Purified recombinant rat synapsin-2.

Application

Anti-Synapsin-2 Antibody, clone 19.4 is an antibody against Synapsin-2 for use in Western Blotting, Immunohistochemistry (Paraffin), Immunoprecipitation, Enzyme Assay.

Immunohistochemistry Analysis: A 1:1,000 dilution from a representative lot detected Synapsin-2 in human cerebral cortex, mouse cerebellum, and rat cerebral cortex tissue.
Western Blotting Analysis: Target detection by a representative lot was blocked by a preincubation with phage particles displaying peptides containing the SYIxN consensus sequence (Vaccaro, P., et al. (1997). Brain Res. Mol. Brain Res. 52(1):1-16).
Western Blotting Analysis: A representative lot detected synapsin IIa/IIb, but not Ia/Ib, in rat brain cytosolic extracts (Vaccaro, P., et al. (1997). Brain Res. Mol. Brain Res. 52(1):1-16).
Immunoprecipitation Analysis: A representative lot immunoprecipitated synapsin IIa/IIb, but not Ia/Ib, from rat brain synaptosomal preparations (Vaccaro, P., et al. (1997). Brain Res. Mol. Brain Res. 52(1):1-16).
Enzyme Assay Analysis: A representative lot, when added 2 hours prior to cAMP, prevented PKA-catalyzed phosphorylation of synapsin IIa/IIb in an in vitro kinase assay using rat brain synaptosomal preparations (Vaccaro, P., et al. (1997). Brain Res. Mol. Brain Res. 52(1):1-16).
