These results are consistent with a model for cell-type specific regulation in which binding of the NF-muNR repressor to the IgH enhancer prevents nuclear matrix attachment in inappropriate cells by interfering with MAR-BP1 /enhancer interaction .
 DNA: /enhancer; protein: IgH; protein: NF-muNR repressor; protein: MAR-BP1; DNA: IgH enhancer; protein: NF-muNR
