One of the latter elements, the IgH 3' enhancer , is of particular interest: (1) it is B cell-specific and active only in late B cell development ; (2) in rodent plasmacytomas and in some human Burkitt's lymphomas it is part of a locus control region ( LCR ) that is involved in deregulation of the c-myc oncogene as a result of translocation into the IgH locus ; and (3) it has been implicated in the mechanisms that control Ig gene class switch recombination.
