Phospho-Ser603 Synapsin I Antibody

Affinity purified rabbit polyclonal antibody

     
  • WB - Phospho-Ser603 Synapsin I  Antibody AN1025
    Western blot of rat cortex lysate showing specific immunolabeling of the ~78k synapsin I phosphorylated at Ser603 (Control). The phosphospecificity of this labeling is shown in the second lane (lambda-phosphatase: λ-Ptase). The blot is identical to the control except that it was incubated in λ-Ptase (1200 units for 30 min) before being exposed to the phospho-Ser603 synapsin I antibody. The immunolabeling is completely eliminated by treatment with λ-Ptase.

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. Th e role of synapsin in synaptic plasticity and in synaptogensis is regulated by phosphorylation (Jovanovic et al., 2001; Kao et al., 2002). Serine 603 is the site on synapsin I that is phosphorylated by calcium calmodulin kinase II and by p21-activated kinases (Sakurada et al., 2002; Czernik et al., 1987). Phosphorylation of this site is thought to regulate synaptic vesicle function (Nayak et al., 1996; Bahler and Greengard, 1987; McGuinness et al., 1989).
