| Gene Symbol | SNAP23 |
| Full Name | Synaptosomal-Associated Protein 23 |
| Chromosomal Location | 15q21.3 |
| NCBI Gene ID | 8773 |

| Gene Family | SNAP receptor (SNARE) |
| Protein Class | Membrane fusion protein |
The SNAP23 gene encodes Synaptosomal-Associated Protein 23, a member of the SNARE (Soluble N-ethylmaleimide-sensitive factor Attachment Protein Receptor) family. SNAP23 is essential for synaptic vesicle fusion, exocytosis, and membrane trafficking in all cell types. It mediates the fusion of synaptic vesicles with the presynaptic membrane during neurotransmitter release and plays crucial roles in various cellular trafficking pathways.
| Domain | Function |
|---|---|
| N-terminal prefix | Regulatory function |
| SNARE motif (x3) | Core coiled-coil domain |
| C-terminal transmembrane | Membrane anchoring |
SNAP23 forms ternary SNARE complexes:
The assembled 4-helix bundle drives membrane fusion.
| Regulator | Mechanism |
|---|---|
| Munc18 | Syntaxin binding |
| Munc13 | Priming function |
| Complexin | Clamp release |
| NSF/α-SNAP | Disassembly |
The study of Snap23 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
