Synapsin I: ELISA Kits

Synapsin I is a neuron-specific, O-GlcNAcylated phosphoprotein that interacts with synaptic vesicles and regulates neurotransmitter release. It is concentrated in pre-synaptic terminals where it anchors synaptic vesicles to the underlying cytoskeleton. Phosphorylation at various sites reduces synapsin I binding to neurosecretory vesicles, making them available for neurotransmitter release.
