Description:
High Mobility Group (HMG) AT-hook 2 (HMGA2) is a member of the HMGA non-histone chromosomal protein family. HMG proteins function as architectural proteins with critical roles in chromatin organization and diverse cellular processes including cell cycle progression, proliferation, differentiation and senescence. They are characterized by the presence of 3 copies of a conserved DNA-binding peptide motif (AT-hook) that preferentially binds with the minor groove of many AT-rich promoter and enhancer DNA regulatory elements. HMGA2 is a downstream target of the let-7 family of miRNAs, which functions as a key regulator of stage-specific transcriptional networks during erythroid development. The let-7 pathway has been reported to be involved in the modulation of fetal haemoglobin (HbF) levels. HMGA2 mRNA is negatively-regulated by the binding of let-7 miRNAs to the 3’-UTR region. HMGA2 is implicated in fetal γ-globin gene expression in human adult erythroblasts.
