Syntaxin-2 is a protein that in humans is encoded by the STX2 gene.[1][2][3]

The product of this gene belongs to the syntaxin/epimorphin family of proteins. The syntaxins are a large protein family implicated in the targeting and fusion of intracellular transport vesicles. The product of this gene regulates epithelial-mesenchymal interactions and epithelial cell morphogenesis and activation. Alternatively spliced transcript variants encoding different isoforms have been identified.[3]

Interactions

STX2 has been shown to interact with SNAP-25,[4][5] SNAP23,[5][6][7][8] STXBP1[4][9] and Syntaxin binding protein 3.[9]
