High mobility group AT-hook 1

HMGA1a, HMGA1, HMGI(Y)
This gene encodes a non-histone protein involved in many cellular processes, including regulation of inducible gene transcription, integration of retroviruses into chromosomes, and the metastatic progression of cancer cells. The encoded protein preferentially binds to the minor groove of A+T-rich regions in double-stranded DNA. It has little secondary structure in solution but assumes distinct conformations when bound to substrates such as DNA or other proteins. The encoded protein is frequently acetylated and is found in the nucleus. At least seven transcript variants encoding two different isoforms have been found for this gene.

Epigenetic Mechanisms Leading to Overexpression of HMGA Proteins in Human Pituitary Adenomas.
Review
Fusco et al., Napoli, Italy. In Front Med (lausanne), 2014

Review
Eilebrecht et al., In Biomolecules, 2014
The high mobility group protein A1 (HMGA1) is a master regulator of chromatin structure mediating its major gene regulatory activity by direct interactions with A/T-rich DNA sequences located in the promoter and enhancer regions of a large variety of genes.
