Products of a reciprocal chromosome translocation involving the c-myc gene in a murine plasmacytoma

Proc Natl Acad Sci U S A. 1984 Feb;81(3):829-33. doi: 10.1073/pnas.81.3.829.


The structures of the rearranged c-myc gene products derived from a rcp T(12;15) have been investigated in the MPC-11 (IgG2b kappa) plasmacytoma. The rcp T(12;15) in MPC-11 is a reciprocal exchange between the c-myc gene on chromosome 15 and the immunoglobulin gamma 2a switch region (S gamma 2a) on chromosome 12. The c-myc gene is broken within a 5'-nontranslated exon, thereby separating the promoter region of the normal c-myc gene from its protein coding sequences. This reciprocal rearrangement results in the loss of 11 base pairs of c-myc sequence and 300 base pairs of S gamma 2a sequence at the point of recombination. Sequences that represent the promoter region of the normal c-myc gene are present in the 5'-myc reciprocal fragment. A comparison of the nucleotide sequences at the recombination site of a number of c-myc rearrangements reveals a common feature that may have mechanistic importance for these translocation events.
