CC   -!- FUNCTION: Plasma membrane t-SNARE that mediates docking of transport
CC       vesicles (By similarity). Necessary for the translocation of SLC2A4
CC       from intracellular vesicles to the plasma membrane (By similarity). In
CC       neurons, recruited at neurite tips to membrane domains rich in the
CC       phospholipid 1-oleoyl-2-palmitoyl-PC (OPPC) which promotes neurite tip
CC       surface expression of the dopamine transporter SLC6A3/DAT by
CC       facilitating fusion of SLC6A3-containing transport vesicles with the
CC       plasma membrane (By similarity). Together with STXB3 and VAMP2, may
CC       also play a role in docking/fusion of intracellular GLUT4-containing
CC       vesicles with the cell surface in adipocytes and in docking of synaptic
CC       vesicles at presynaptic active zones (By similarity).
CC       {ECO:0000250|UniProtKB:P70452, ECO:0000250|UniProtKB:Q08850}.
CC   -!- SUBUNIT: Component of the SNARE complex composed of STX4, SNAP23 and
CC       VAMP7 that interacts with SYT7 during lysosomal exocytosis. Found in a
CC       complex with VAMP8 and SNAP23. Detected in a complex with SNAP23 and
CC       STXBP4. Interacts with VAMP2. Interacts with SNAP23 and SNAPIN.
CC       Interacts with LLGL1. Interacts (via C-terminus) with CENPF. Interacts
CC       with DOC2B. Interacts with STXBP6. Interacts with STXBP3; excludes
CC       interaction with DOC2B and SNAP25. Interacts with STXBP4; excludes
CC       interaction with VAMP2 (By similarity). Interacts with STXBP5L (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q08850};
CC       Single-pass type IV membrane protein {ECO:0000305}. Cell projection,
CC       neuron projection {ECO:0000250|UniProtKB:Q08850}. Note=Localizes to
CC       neurite tips in neuronal cells. {ECO:0000250|UniProtKB:Q08850}.
CC   -!- SIMILARITY: Belongs to the syntaxin family. {ECO:0000305}.
