May play a role in retrograde transport of proteins from the Golgi to the endoplasmic reticulum. May indirectly play a role in protein glycosylation in the Golgi.
Subcellular locations: Golgi apparatus, Golgi stack membrane
Expressed strongly in kidney and skeletal muscle, followed by liver, placenta, pancreas, and lung, with low amounts in heart and only traces in brain . Widely expressed with ubiquitous expression in epithelial tissues (at protein level) .
