FIG. 7.
The mutant TBPAS rescues transcription of position 2 CATA box mutants. Shown are three CATA box mutants in the subtype B (A) and E (B) contexts. Control transfections (−) and cotransfections with TBPwt and TBPAS were performed. No significant differences were observed between control transfections and cotransfection with TBPwt. There were significant differences only between cotransfections with TBPAS and TBPwt, which were determined by a paired t test (*, P < 0.05; **, P < 0.01; ***, P < 0.001; n.s., not significant). Error bars indicate standard errors.
