MeSH definition : An AT-hook motif-containing protein (AT-HOOK MOTIFS) that binds to the minor grove
of AT-rich regions of DNA. It is a truncated form of HMGA1a protein that is produced
by alternative-splicing of the HMGA1 gene. It may function as an architectural chromatin
binding protein that is involved in transcriptional regulation.;
MeSH synonym : at-hook 1b protein, high mobility group; hmgy protein; at hook 1b protein, high mobility group;
