Synapsin I plays a key role in synaptic plasticity in brain (Feng et al., 2002; Nayak etal., 1996). This effect is due in large part to the ability of the synapsins to regulate the availability ofsynaptic vesicles for release. The role of synapsin in synaptic plasticity and in synaptogensis isregulated by phosphorylation (Jovanovic et al., 2001; Kao et al., 2002). Serine 603 is the site onsynapsin 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 regulatesynaptic vesicle function (Nayak et al., 1996; Bahler and Greengard, 1987; McGuinness et al.,1989).
