Target

  • Function
    HMG-I/Y bind preferentially to the minor groove of A+T rich regions in double stranded DNA. It is suggested that these proteins could function in nucleosome phasing and in the 3'-end processing of mRNA transcripts. They are also involved in the transcription regulation of genes containing, or in close proximity to A+T-rich regions.
  • Involvement in disease
    Note=A chromosomal aberration involving HMGA1 is found in pulmonary chondroid hamartoma. Translocation t(6;14)(p21;q23-24) with RAD51L1.
  • Sequence similarities
    Belongs to the HMGA family.
    Contains 3 A.T hook DNA-binding domains.
  • Post-translational
    modifications
    Constitutively phosphorylated on two or three sites. Phosphorylated upon DNA damage, probably by ATM or ATR. Hyperphosphorylated at early stages of apoptosis, followed by dephosphorylation and methylation, which coincides with chromatin condensation. Isoform HMG-Y can be phosphorylated by HIPK2.
    HMG-Y is not methylated.
    Methylation at Arg-58 is mutually exclusive with methylation at Arg-60.
