SLC30A4 encodes the human gene, Solute carrier family 30 (zinc transporter), member 4. It may also be known as: Zinc transporter 4; Solute carrier family 30 member 4; ZnT-4; ZNT4. The encoded protein has an amino acid length of 429 and a mass of 47.5 kDa. Other isoforms may exist. SLC30A4 is a member of the Cation diffusion facilitator (CDF) transporter (TC 2.A.4) family, SLC30A subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
