Western blot of rat cortex lysate showing specific immunolabeling of the ~78 kDa synapsin I phosphorylated at Ser549 (Control). The phosphospecificity of this labeling is shown in the second lane (lambda-phosphatase). The blot is identical to the control except that it was incubated in L-Ptase (1200 units for 30 min) before being exposed to the phospho Ser549 synapsin I antibody. The immunolabeling is completely eliminated by treatment with L-Ptase.

This antibody is predicted to react with bovine, canine, human, mouse and non-human primate based on 100% sequence homology.
In Western blot, this antibody is specific for ~78 kDa synapsin I doublet phosphorylated at Ser549. Immunolabeling can be blocked by lambda-phosphatase treatment.
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. The role of synapsin in synaptic plasticity and in synaptogensis is regulated by phosphorylation (Jovanovic et al., 2001; Kao et al., 2002). Ser 549 along with Ser 62 and Ser 67 are the sites of synapsin I that are phosphorylated by MAP kinase (Jovanovic et al., 1996). Phosphorylation and subsequent dephosphorylation of this site is thought to play a key role in synaptic vesicle trafficking.
