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.
