SNAPN_MOUSE - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: SNAPN_MOUSE
• UniProt AC: Q9Z266
• Protein Name: SNARE-associated protein Snapin
• Gene Name: Snapin
• Organism: Mus musculus (Mouse).
• Sequence Length: 136
• Subcellular Localization: Membrane ; Peripheral membrane protein ; Cytoplasmic side . Cytoplasm, cytosol . Cytoplasm, perinuclear region . Golgi apparatus membrane . Lysosome membrane . Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane . Colocalizes with NANOS
• Protein Description: Component of the BLOC-1 complex, a complex that is required for normal biogenesis of lysosome-related organelles (LRO), such as platelet dense granules and melanosomes. In concert with the AP-3 complex, the BLOC-1 complex is required to target membrane protein cargos into vesicles assembled at cell bodies for delivery into neurites and nerve terminals. The BLOC-1 complex, in association with SNARE proteins, is also proposed to be involved in neurite extension. Plays a role in intracellular vesicle trafficking and synaptic vesicle recycling. May modulate a step between vesicle priming, fusion and calcium-dependent neurotransmitter release through its ability to potentiate the interaction of synaptotagmin with the SNAREs and the plasma-membrane-associated protein SNAP25. Its phosphorylation state influences exocytotic protein interactions and may regulate synaptic vesicle exocytosis. May also have a role in the mechanisms of SNARE-mediated membrane fusion in non-neuronal cells. [PubMed: 16760431]
