Snapin Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
SNAPIN (SNAP Associated Protein) is a 163-amino acid protein that functions as a component of the SNARE (Soluble N-ethylmaleimide-sensitive fusion protein Attachment protein REceptor) complex. It plays a critical role in synaptic vesicle trafficking and neurotransmitter release.

SNAPIN possesses a relatively simple structure optimized for its role in synaptic vesicle fusion:
SNAPIN participates in SNARE complex formation:
SNAPIN functions at multiple stages:
| Partner | Interaction Type | Function |
|---|---|---|
| SNAP-25 | Direct binding | Core SNARE complex |
| Synaptotagmin | Calcium sensor | Ca²⁺-triggered release |
| CSPα | Chaperone complex | Synaptic integrity |
| Hsc70 | Chaperone | Protein folding |
| LGI1 | ADAM22 complex | Synaptic transmission |
SNAPIN is expressed throughout the nervous system:
Expression is maintained in adults, with highest levels in regions with high synaptic activity.
SNAPIN involvement in AD:
| Strategy | Approach | Status |
|---|---|---|
| SNARE modulators | Enhance/complex function | Preclinical |
| Gene therapy | AAV-SNAPIN delivery | Research |
| Autophagy enhancers | Improve protein clearance | Research |
