Background

Syntaxin 5 (STX5) is a predicted 41‑42 kDa member of the syntaxin family of proteins. It is a t‑SNARE that is widely expressed (but not in striated muscle), and embedded in either the cis‑Golgi network (a 37 kDa form) or the ER (the 46 kDa form). STX5 is involved in the regeneration and maintenance of the Golgi apparatus after mitosis. Human STX5 is a type IV single‑pass transmembrane protein (very long cytoplasmic N‑terminus) that is 355 amino acids (aa) in length. It contains an ER retrieval signal (Arg4Lys5Arg6), a t‑SNARE domain (aa 263‑325) with a coiled‑coil region (aa 287‑318), and a C‑terminal transmembrane sequence. The 35 kDa short form exhibits an alternate start site at Met55. Two other potential splice variants show either the Met55, or a Met97 start site coupled to a 19 aa substitution for aa 303‑355. Over aa 55‑300, human STX5 shares 94% aa identity with mouse STX5.
