SNAP29 encodes a Q-SNARE protein involved in multiple membrane fusion events throughout the cell. SNAP29 participates in synaptic vesicle release, endolysosomal trafficking, and autophagosome-lysosome fusion. It is essential for protein quality control through autophagy and is implicated in various neurodegenerative diseases.
SNAP29 contains typical SNARE motifs:
