Predicted to enable SNAP receptor activity and SNARE binding activity. Predicted to be involved in several processes, including cholesterol efflux; organelle fusion; and protein stabilization. Predicted to act upstream of or within protein transport. Predicted to be located in several cellular components, including membrane raft; phagocytic vesicle; and phagophore assembly site. Predicted to be part of BLOC-1 complex and SNARE complex. Predicted to be active in postsynaptic recycling endosome and synaptic vesicle. Predicted to be integral component of synaptic vesicle membrane. Is expressed in cranial ganglion; dorsal root ganglion; hindbrain; and sensory organ. Orthologous to human STX12 (syntaxin 12).
