Expressed in kidney proximal tubule cells, placenta, visceral yolk-sac cells and in absorptive intestinal cells. Expressed in the epithelium of intestine and kidney.
Apical cell membrane; Peripheral membrane protein. Cell membrane; Peripheral membrane protein. Membrane, coated pit. Endosome. Lysosome membrane; Peripheral membrane protein. Lacks a transmembrane domain and depends on interaction with AMN for location at the plasma membrane (PubMed:29402915, PubMed:30523278). Colocalizes with AMN and LRP2 in the endocytotic apparatus of epithelial cells (By similarity).
