DNA binding domain with preference for A/T rich regions
SMART accession number:SM00384
Description: Small DNA-binding motif first described in the high mobility group non-histone chromosomal protein HMG-I(Y).
Interpro abstract (IPR017956):

AT hooks are DNA-binding motifs with a preference for A/T rich regions. These motifs are found in a variety of proteins, including the high mobility group (HMG) proteins [(PUBMED:11406267)], in DNA-binding proteins from plants [(PUBMED:8790293)] and in hBRG1 protein, a central ATPase of the human switching/sucrose non-fermenting (SWI/SNF) remodeling complex [(PUBMED:17081121)].

GO function:DNA binding (GO:0003677)
