function:Probably plays a role in the control of regulated secretion in neural and endocrine cells.,PTM:N-glycosylated.,PTM:The N-terminal cytoplasmic domain is phosphorylated by CK1.,similarity:Belongs to the major facilitator superfamily.,subcellular location:Associated with synaptic-like microvesicles but not with insulin-containing vesicles in insulin-secreting cells of the pancreas. Localizes to microvesicles in the pinealocytes. Localizes to the acrosome in spermatids.,subunit:Interacts with SYT1 in a calcium-independent manner. Forms a complex with SYT1, syntaxin-1 and SNAP25.,
