Genomic and promoter structure of mouse Irg GTPases. (a) Genomic structure of mouse Irg genes. Green blocks indicate coding exons and blue blocks indicate 5'-untranslated exons. Orange arrows identify putative promoter regions. Stars identify exons shown to be excluded in alternative splice forms. The scale bar is measured in base pairs up to the first base of the long coding exon. Note the presence of two promoters for Irga6 and Irgd. (b) Interferon response elements in the promoter regions of mouse Irg genes. γ-Activated sequences (GAS; pale blue blocks) and interferon-stimulated response element (ISRE; red blocks) sequences were identified in the promoters shown in panel a (also see Additional data file 7). Dark blue blocks downstream of each promoter represent the most 5' exon. The yellow block identifies a putative Sox1 transcription factor binding site in the proximal promoter region of Irgc. The scale bar is measured in base pairs from the first base of the 5' exon.
