Colocalization of ferroportin-1 with hephaestin on the basolateral membrane of human intestinal absorptive cells

An iron exporter ferroportin‐1 (FPN‐1) and a multi‐copper oxidase hephaestin (Heph) are predicted to be expressed on the basolateral membrane of the enterocyte and involved in the processes of iron export across the basolateral membrane of the enterocyte. However, it is not clear where these proteins are exactly located in the intestinal absorptive cell. We examined cellular localization of FPN‐1 and Heph in the intestinal absorptive cells using...
