HMGA1
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. Belongs to the HMGA family. 3 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
