Abstract excerpt
Sex-reversal mutations in human SRY cluster within its high-mobility group box, a conserved motif of DNA bending. A classical substitution at the crux of this angular domain (M64I) has been reported to impair DNA bending but not DNA binding, implying that sharp bending is required for transcriptional activation and testis determination. Surprisingly, we report that this defect was an inadvertent consequence of...
