Syntaxin 3, also known as STX3, is a protein^[5] which in humans is encoded by the STX3 gene.^[6]^[7]

Function

The protein encoded by this gene is a member of the syntaxin family of cellular receptors for transport vesicles which participate in exocytosis in neutrophils.^[6] STX3 has an important role in the growth of neurites and serves as a direct target for omega-6 arachidonic acid.^[8] Mutations in Syntaxin 3 cause Microvillus inclusion disease.^[9]

Interactions

Syntaxin 3 has been shown to interact with SNAP-25,^[10]^[11]^[12] SNAP23^[11]^[12]^[13]^[14] and SNAP29.^[12]
