Riox1 and Riox2 gene structures. a The human RIOX2 gene exhibits ten exons distributed on chromosome 3. The exon lengths are indicated. The RIOX2 protein domains (JmjC, dimerization, WH) were mapped on the gene. b The human RIOX1 gene is a single exon gene of 1962 bases on chromosome 14. The RIOX1 protein domains (JmjC, dimerization, WH) were mapped on the gene. c Analysis of the genomic structures of Riox2 and Riox1 genes in H. sapiens, M. musculus, G. gallus, X. laevis, D. rerio, C. elegans, D. melanogaster and H. vulgaris with the number of exons are given in the Table. C. elegans and D. melanogaster lack a Riox1 gene. The Riox2 genes of human (Hs), mouse (Mm) and chicken (Gg) exhibit one non-coding exon (5’) and nine coding exons
