Potential role in vesicular protein trafficking, mainly in the early secretory pathway. Contributes to the coupled localization of TMED2 and TMED10 in the cis-Golgi network.
Subcellular locations: Endoplasmic reticulum-Golgi intermediate compartment membrane, Golgi apparatus, Cis-Golgi network membrane, Golgi apparatus, Golgi stack membrane, Endoplasmic reticulum membrane, Cytoplasmic vesicle, COPI-coated vesicle membrane
Probably cycles between compartments of the early secretatory pathway.
