HMGA1 Gene Information

HGNC symbol
HMGA1 
Aliases
HMGIY 
Common name
high mobility group AT-hook 1 
Entrez Id
3159
Description
This gene encodes a chromatin-associated protein involved in the regulation of gene transcription, integration of retroviruses into chromosomes, and the metastatic progression of cancer cells. The encoded protein preferentially binds to the minor groove of AT-rich regions in double-stranded DNA. Multiple transcript variants encoding different isoforms have been found for this gene. Pseudogenes of this gene have been identified on multiple chromosomes. [provided by RefSeq, Jan 2016].
