| Post Translational Modifications | Substrate of different protein kinases. Phosphorylated by CaMK2 and MAPK1. Phosphorylation, including phosphorylation at Ser-9, promotes synapsin-1 dissociation from synaptic vesicles, regulates its rate of dispersion, and controls the kinetics of vesicle pool turnover and neurotransmitter release . |
| Function | Neuronal phosphoprotein that coats synaptic vesicles, and binds to the cytoskeleton. Acts as a regulator of synaptic vesicles trafficking, involved in the control of neurotransmitter release at the pre-synaptic terminal. Also involved in the regulation of axon outgrowth and synaptogenesis. The complex formed with NOS1 and CAPON proteins is necessary for specific nitric-oxid functions at a presynaptic level. |
