Snap25 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.
SNAP25 is a gene/protein encoding a key neuronal protein involved in synaptic function, signal transduction, and cellular homeostasis. Dysfunction of SNAP25 is associated with neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and related disorders.
Protein Name: SNAP-25 (Synaptosomal-Associated Protein 25)
Gene: SNAP25
UniProt ID: P60880
Molecular Weight: 25 kDa
Subcellular Localization: Presynaptic plasma membrane (attached via palmitoylation)

SNAP-25 has a distinctive architecture:
The protein lacks a transmembrane domain and is anchored via palmitoyl groups attached to cysteine residues[1].
SNAP-25 is essential for neurotransmitter release:
SNAP-25 participates in:
Two major isoforms:
SNAP25 alterations in AD:
In PD:
SNAP25 mutations and changes:
