Fig. 2From: Zinc transporters and insulin resistance: therapeutic implications for type 2 diabetes and metabolic diseasePredicted structure of the zinc transporters ZIP and ZnT. ZIP transporters are predicted to have eight transmembrane domains (TMDs) with a long histidine loop between TMDs 3 and 4. The ZnT transporters are predicted to have six TMDs with a histidine loop between TMDs 4 and 5. Figure was produced using Servier Medical Art, http://www.servier.com Back to article page
