AT Hook Motif Definition

Highly conserved peptide motifs of the HMG-I(Y) proteins that preferentially bind, in vivo and in vitro, to the narrow minor groove of stretches of AT-rich DNA. The AT Hook Motif tethers and unbends the minor groove of the DNA with very little specificity for the DNA sequence. The AT hook motif has a narrow DNA recognize surface which is devoid of hydrophobic amino acids and does not significantly distort the B-form DNA structure.

AT Hook Motif Synonyms
