Chromosomal location of the human SLC11A1 and SLC11A2 genes (A) and SLC11 gene loci in teleost species (B). (A) Paralogs of gene families with multiple members are shown below each ORF, with distance in Mb to the p telomere of the respective chromosome. (B) Below the G. aculeatus loci, the location of teleost specific 3R paralogs is shown; also the genomic mapping position of human orthologs is presented. Ga - Gasterosteus aculeatus, Dr - Danio rerio, Ol - Oryzias latipes, Tn - Tetraodon nigroviridis, Tr - Takifugu rubribes, Dl - Dicentrarchus labrax. Arrows denote gene orientation.
