Protocols

Specificity / Sensitivity

Phospho-Synapsin (Ser9) Antibody detects endogenous levels of synapsin only when phosphorylated at serine 9. The antibody is expected to recognize phosphorylated serine 9 of all synapsin isoforms.

Source / Purification

Polyclonal antibodies are produced by immunizing rabbits with a synthetic phospho-peptide (KLH-coupled) corresponding to residues surrounding serine 9 of human synapsin I. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of mouse brain homogenates, untreated or phosphatase-treated, using Phospho-Synapsin (Ser9) Antibody (upper) or Synapsin Antibody #2312 (lower).

Background

Synapsins, a group of at least five related members (synapsins Ia, Ib, IIa, IIb and IIIa), are abundant brain proteins essential for regulating neurotransmitter release (1,2). All synapsins contain a short amino-terminal domain that is highly conserved and phosphorylated by PKA or CaM kinase I (1). Phosphorylation of synapsin amino-terminal domain at serine 9 inhibits its binding to phospholipids and dissociates synapsins from synaptic vesicles (2).
