Hmga2 Gene Summary [Rat]
Enables enzyme binding activity. Involved in negative regulation of signal transduction and regulation of DNA-templated transcription. Predicted to be located in male germ cell nucleus; nuclear chromosome; and senescence-associated heterochromatin focus. Predicted to be part of SMAD protein complex and protein-DNA complex. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in Silver-Russell syndrome; leiomyoma; lipoma; and ovarian cancer. Orthologous to human HMGA2 (high mobility group AT-hook 2). [provided by Alliance of Genome Resources, Jul 2025]
