Western Blot (WB)
app notes :
Quality Control: Western blots performed on each lot. WB: 1:1000
other info1 :
Antigen: Phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser603 of synapsin I. Immunogen Information: Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser603 conjugated to KLH. Immunogen Species: Rat
other info2 :
Reactivity Assumed Based on 100% Sequence Homology: Human, Xenopus, bovine, mouse, zebra fish. Species Reactivity Note: The antibody has been directly tested for reactivity in Western blots with rat tissue. It is anticipated that the antibody will react with bovine, human, mouse, Xenopus and zebra fish tissue based on the fact that these species have 100% homology with the amino acid sequence used as antigen.
products description :
Affinity purified rabbit polyclonal antibody. 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). 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).
