    text
  • is expressed in early endosomes, where it promotes the assimilation of iron from transferrin
  • basic FUNCTION
  • would be involved in heavy metal ion transport
  • involved in the control of intracellular zinc homoeostasis
  • glycosylated protein functioning as a zinc influx transporter in a temperature-dependant manner
  • plays a role as a zinc transporter during the early stages of adipogenesis
  • can mediate the uptake of zinc and non-transferrin-bound iron into cells and it may play a role in zinc and iron metabolism in hepatocytes, where this transporter is abundantly expressed
  • like SLC39A8, SLC39A14 proteins are glycosylated
  • can mediate the transport of iron at pH 6.5, the pH at which iron dissociates from transferrin within the endosome
  • endosomal form potentially participates in the cellular assimilation of iron from transferrin, thus identifying a potentially new role in iron metabolism
  • potentially playing a role in placental iron transfer
  • can participates in the assimilation of iron from transferrin in addition to playing a role in non-transferrin-bound iron uptake
  • controls G-Protein coupled receptor-mediated signaling required for systemic growth
  • can transport iron, zinc, manganese, and cadmium
  • plays more of a role than SLC11A2 in iron overload
  • may not only function during iron overload to take up non-transferrin-bound iron (NTBI), but also under normal or iron-deficient conditions when cells take up iron via endocytosis of transferrin
  • SLC30A10 and SLC39A14 are manganese efflux and influx transporters, respectively
  • transport activities of both SLC39A14 and SLC30A10 are required for hepatic manganese excretion
