STX5 (Syntaxin 5) is a SNARE protein localized to the Golgi apparatus, where it mediates vesicular transport between the ER and Golgi. STX5 is essential for protein sorting and has been studied in the context of neurodegeneration due to its role in trafficking proteins involved in aggregate clearance.

STX5 encodes syntaxin 5, a Golgi-localized SNARE protein essential for ER-Golgi transport and intra-Golgi trafficking. Syntaxin 5 is the primary t-SNARE for COPII-mediated ER export and mediates Golgi cisternal maturation. In neurons, syntaxin 5 is crucial for the trafficking of synaptic proteins, neuropeptides, and amyloid precursor protein (APP). Dysregulation of syntaxin 5 function has been linked to Alzheimer's disease through altered APP processing and trafficking.
Ubiquitously expressed with high levels in brain. In neurons, involved in trafficking of synaptic components and secretory proteins.
