Protein Domain : Snapin IPR017246

Type	Family
Description	Snapin is a component of the biogenesis of lysosomal organelles complex-1 (BLOC-1), a complex required for the normal biogenesis of lysosome-related organelles, such as melanosomes and platelet dense granules [ ], and endosomal cargo sorting [].Snapin binds to SNAP-25, part of the SNARE complex that mediates the synaptic vesicle docking and fusion [ ]. Snapin 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 [, ]. It may also have a role in the mechanisms of SNARE-mediated membrane fusion in non-neuronal cells [].
