Gene Summary
Synapsin (Syn) encodes a phosphoprotein associated with synaptic vesicles. It interacts with the endocytic scaffolding protein encoded by Dap160. Phosphorylation of synapsin at serine 6 is required for associative short-term learning/memory and short-term olfactory habituation. It is important for outgrowth of synaptic boutons at the larval neuromuscular junction. [Date last reviewed: 2019-03-14] (FlyBase Gene Snapshot)

Protein Function (UniProtKB)
Plays a significant role in nervous system function, which is subtle at the cellular level but manifests itself in complex behavior.
(UniProt, Q24546)
Summary (Interactive Fly)

a vescular protein that participates in the regulation of neurotransmitter release - interacts with the cytoskeleton to regulate the number of synaptic vesicles available for release via exocytosis - promotes vesicle reuptake and reserve pool formation upon intense stimulation

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

          Syn regulates activity-dependent outgrowth of synaptic boutons at the neuromuscular junction.

          dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.

          Syn is cloned and characterised, a 309 amino acid domain shows 50% identity to the C domain of vertebrate synapsins.

          The predicted amino acid sequence of the Syn gene product displays significant homology to the synaptic vesicle associated protein Synapse I from vertebrates.
