SRY and human sex determination: the basic tail of the HMG box functions as a kinetic clamp to augment DNA bending.

Abstract excerpt

Human testis-determining factor SRY contains a high-mobility-group (HMG) box, an alpha-helical DNA-binding domain that binds within an expanded minor groove to induce DNA bending. This motif is flanked on the C-terminal end by a basic tail, which functions both as a nuclear localization signal and accessory DNA-binding element. Whereas the HMG box is broadly conserved among otherwise unrelated transcription...
