Ke4, or Solute carrier family 39 (zinc transporter), member 7, is a human gene encoded by SLC39A7. It may also be known as: Zinc transporter SLC39A7; Really interesting new gene 5 protein; Solute carrier family 39 member 7; Zrt-, Irt-like protein 7; ZIP7; Histidine-rich membrane protein Ke4; D6S115E; D6S2244E; H2-KE4; HKE4; KE4. The encoded protein has an amino acid length of 469 and a mass of 50.1 kDa. Ke4 is a member of the ZIP transporter (TC 2.A.5) family, KE4/Catsup subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog.
