DATASHEET

Host: Rabbit

Target Protein: Synapsin I (Ser9)

Specificity: Specific for endogenous levels of the ~78 kDa synapsin I doublet protein phosphorylated at Ser9. Also weakly labels the ~55 kDa synapsin II protein which has a similar phosphorylation site to that of Ser9 on synapsin I. Immunolabeling is completely eliminated by treatment with λ-phosphatase.

Modification Site: Ser9

Clonality: Polyclonal

Isotype: IgG

Entrez Gene: 281510

Swiss Prot: P17599

Source: Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser9 of rat synapsin, conjugated to keyhole limpet hemocyanin (KLH).

Purification: Antigen Affinity purification from Pooled whole antiserum

Storage Buffer: 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.

Storage: Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Background:

Synapsin I plays a key role in synaptic plasticity in brain (Feng et al., 2002; Nayak et al., 1996). This effect is due in large part to the ability of the synapsins to regulate the availability of synaptic vesicles for release. In addition to its role in plasticity, the expression of synapsin I is a precise indicator of synapse formation (Moore and Bernstein, 1989; Stone et al., 1994). Thus, synapsin I immunocytochemistry provides a valuable tool for the study of synaptogenesis. The role of synapsin in synaptic plasticity and in synaptogenesis is regulated by phosphorylation (Jovanovic et al., 2001; Kao et al., 2002). Serine 9 is the site on synapsin I that is phosphorylated by cAMP-dependent protein kinase and by calcium calmodulin kinase I (Czernik et al., 1987). Phosphorylation of this site is thought to regulate synaptic vesicle function and neurite outgrowth (Kao et al., 2002).
