Expression of RNA pol III targets in mafr-1 RNAi treated animals (A) or animals overexpressing (O/E) mafr-1 (B). Expression of human RNA pol III targets in 293T cells transfected with mafr-1 or Maf1 (C). Expression of the RNA pol II target tbp-1/TBP (D). Developmental expression pattern of mafr-1 mRNA (E) and MAFR-1::GFP protein (F). MAFR-1 tissue expression revealed by imaging animals expressing MAFR-1::GFP DIC (G) (A, anterior and P, posterior), intestinal cells (H) (arrows), and hypodermal cells (I) (arrow heads). Data are presented as mean ± SEM. *P < 0.05, **P < 0.01, ***P<0.001 versus respective controls. Scale bar = 100um. See also Figure S1.
