Intermolecular recombination of human c-myb proto-oncogene coding sequences.

We have previously reported evidence suggesting that intermolecular recombination events are involved in the tissue specific expression of the c-myb proto-oncogene in chicken. We show in this paper that recombined c-myb mRNA species are also expressed in human thymic cells, therefore indicating that intermolecular recombination of coding sequences occurs in higher eucaryotes.
