Coexpression of HMG I/Y and Oct-2 in cell lines lacking Oct-2 results in high levels of HLA-DRA gene expression , and in vitro DNA-binding studies reveal that HMG I/Y stimulates Oct-2A binding to the HLA-DRA promoter .
 protein: Oct-2A; protein: Oct-2; DNA: HLA-DRA promoter; protein: I/Y; protein: I/Y; DNA: HLA-DRA gene; protein: HMG I/Y; cell line: cell lines; protein: Oct-2
