Disease:A chromosomal aberration involving HMGA1 is found in pulmonary chondroid hamartoma. Translocation t (6;14) (p21;q23-24) with RAD51L1. ,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. ,mass spectrometry:With 1 acetyl and 2 phosphate groups PubMed:15302935 ,mass spectrometry:With 1 acetyl and 3 phosphate groups PubMed:15302935 ,mass spectrometry:With 1 acetyl , 1 methyl and 2 phosphate groups PubMed:15302935 ,mass spectrometry:With 1 acetyl , 1 methyl and 3 phosphate groups PubMed:15302935 ,mass spectrometry:With 1 acetyl , 2 methyl and 2 phosphate groups PubMed:15302935 ,mass spectrometry:With 1 acetyl , 2 methyl and 3 phosphate groups PubMed:15302935 ,PTM: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. ,PTM:HMG-Y is not methylated. ,PTM:Methylation at Arg-58 is mutually exclusive with methylation at Arg-60. ,similarity:Belongs to the HMGA family. ,similarity:Contains 3 A.T hook DNA-binding domains. ,subunit:Interacts with HIPK2 (By similarity) . Interacts with HIV-1 pre-integration complex. ,
