Functions in endoplasmic reticulum to Golgi vesicle-mediated transport and regulates the proper organization of the endoplasmic reticulum and the Golgi (By similarity). Plays a key role in targeting to neuronal dendrites receptors such as HTR1A (By similarity). Plays also a role in primary cilium and sperm flagellum assembly probably through protein transport to these compartments .
Subcellular locations: Endoplasmic reticulum membrane, Golgi apparatus membrane, Endoplasmic reticulum-Golgi intermediate compartment membrane
Shuttles between the endoplasmic reticulum, the intermediate compartment and the Golgi apparatus.
