1 We show that a 399 bp fragment from the MLL bcr is sufficient to cause a 3-4-fold stimulation of spontaneously occurring DNA exchange and to respond to etoposide by up to 10-fold further elevated frequencies, i.e. to mimic the fragility of the 8.3 kb bcr during chemotherapy. Etoposide lysine methyltransferase 2A Homo sapiens
2 Consistent with the proposed role of p53 as a suppressor of error-prone recombination, both p53 proteins down-regulated recombination with most of the sequences tested, even with the MLL bcr after etoposide treatment. Etoposide lysine methyltransferase 2A Homo sapiens
