Here we show that the lymphoid-specific transcription factor Oct-2A plays a critical role in HLA-DRA gene expression in class II-positive B cell lines , and that the high mobility group protein ( HMG ) I/Y binds to multiple sites within the DRA promoter , including the Oct-2A binding site .
 protein: lymphoid-specific transcription factor; protein: high mobility group protein; DNA: HLA-DRA gene; protein: Oct-2A; DNA: Oct-2A binding site; DNA: DRA promoter; protein: lymphoid-specific transcription factor Oct-2A; protein: HMG; protein: Oct-2A; protein: I/Y; cell line: class II-positive B cell lines
