Synapsin i (syni), a major sv phosphoprotein involved in the regulation of sv trafficking and neurotransmitter release, is one of the presynaptic substrates of cdk5, which phosphorylates it in its c-terminal region at ser(549) (site 6) and ser(551) (site 7). Phosphorylation of syni by cdk5 is physiologically regulated and enhances its binding to f-actin. |

It has been reported that site 1 of syn i can be phosphorylated by pka. Pka-mediated synapsin i ser9 phosphorylation occurs in response to cgs 21680 treatment. Results show that the adenosine a2a receptor agonist, cgs 21680, increases neurotransmitter release, in particular, glutamate and noradrenaline and such response is mediated by protein kinase a activation, which in turn increased synapsin i phosphorylation |

Synapsins are a family of peripheral proteins that bind to the SV membrane. Synapsins Maintain the SV Reserve Pool. Synapsins serve as a key protein for maintaining SVs within this reserve pool, but the mechanism that allows synapsins to do this is unclear. This mechanism is likely to involve synapsins either cross-linking SVs, thereby anchoring SVs to each other, or creating a liquid phase that allows SVs to float within a synapsin droplet. |

Synapsins, a family of neuron-specific phosphoproteins, have been demonstrated to regulate the availability of synaptic vesicles for exocytosis by binding to both synaptic vesicles and the actin cytoskeleton in a phosphorylation-dependent manner. The interaction between synapsin I and Rab3A was confirmed by photoaffinity labeling experiments on purified synaptic vesicles and by the formation of a chemically cross-linked complex between synapsin I and Rab3A in intact nerve terminals. The data indicate that synapsin I is a novel Rab3 interactor on synaptic vesicles and suggest that the synapsin-Rab3 interaction may participate in the regulation of synaptic vesicle trafficking within the nerve terminals. |

Synapsins are exclusively localized to synaptic vesicles, which they coat as peripheral membrane proteins; they probably constitute one of the most abundant neuronal PKA substrates. Our study reveals an unexpectedly dynamic state of synapsins in nerve terminals: any changes in PKA or CaM Kinase I activity will modulate the amount of synapsin on synaptic vesicles.
