High impact information on SLC30A2

  • Gene knockdown of SLC30A2 in mammary epithelial cells reduced zinc secretion, illustrating the role of ZnT-2 in zinc secretion from this cell type [1].
  • Sequencing of genomic DNA detected a mis-sense mutation (Ade-->Gua) that substitutes a conserved histidine at amino acid 54 with arginine (H54R) in SLC30A2 (ZnT-2) that is present in both affected subjects and several other siblings [1].
  • ZnT-2 and ZnT-3 may function in tissue-specific vesicular zinc transport [2].
  • ZnT-2 is also an exporter and may be involved in zinc efflux or uptake into vesicles in intestine, kidney, and testis [3].
