Protein Structure

Function Cargo transport protein that is required for apical transport from the Golgi complex. Transports AQP2 from the trans- Golgi network (TGN) to sites of AQP2 phosphorylation. Mediates the non-vesicular transport of glucosylceramide (GlcCer) from the trans-Golgi network (TGN) to the plasma membrane and plays a pivotal role in the synthesis of complex glycosphingolipids. Binding of both phosphatidylinositol 4-phosphate (PIP) and ARF1 are essential for the GlcCer transfer ability. Also required for primary cilium formation, possibly by being involved in the transport of raft lipids to the apical membrane, and for membrane tubulation. {ECO:0000269PubMed:15107860, ECO:0000269PubMed:16103222, ECO:0000269PubMed:17687330}.
Subcellular Localization Cytoplasm. Golgi apparatus, trans-Golgi network membrane. Membrane; Peripheral membrane protein. Note=Mainly localized to the trans-Golgi network (TGN) but also found at the rims of Golgi cisternae. Associates with ARF1 at Golgi apparatus membranes.
Disease Associations
Tissue Specificity Expressed in kidney cell lines. {ECO:0000269PubMed:15107860}.
