STX3 / Syntaxin 3 Background

STX3, also known as syntaxin 3, belongs to the syntaxin family. STX3 is a target membrane protein (t-SNARE) which is needed for membrane fusion. Membrane fusion requires the formation of a complex between a vesicle protein (v-SNARE) and t-SNAREs. STX3, together with syntaxin 2, are predominantly localized at the plasma membrane. Syntaxin 2 cycles between the plasma membrane and the perinuclear compartment whereas syntaxin 3 cycles between the plasma membrane and the trans-Golgi network. It is possible that this cycling has an important role in the regulation of t-SNARE function.
