We demonstrate that the NF-microB-binding site plays a critical role in the IgH enhancer , because mutation of the microB DNA motif decreased transcriptional activity of the IgH enhancer in cells of the B-cell lineage but not in nonlymphoid cells .
 DNA: IgH enhancer; DNA: NF-microB-binding site; cell type: nonlymphoid cells; DNA: IgH enhancer; cell type: B-cell lineage
