A common site of ecotropic murine leukemia virus integration designated Evi-2 (ecotropic viral integration site-2) has been identified in BXH-2 myeloid tumors. As part of experiments to determine whether Evi-2 identified a new proto-oncogene locus involved in myeloid disease, we determined its chromosomal location. We mapped Evi-2 to mouse Chromosome 11 using standard recombinant inbred strain and genetic backcross analysis. We then determined the location of Evi-2 relative to other proto-oncogene and growth factor loci located on Chromosome 11 by interspecific backcross analysis. The loci included in this study were the proto-oncogene loci, Erbb, Erba, and Rel, as well as, Il-3 (interleukin-3), Csfgm (granulocyte-macrophage colony stimulating factor), and Trp53-1 (transforming protein p53). ALL loci except Erbb had been previously mapped to Chromosome 11 with the use of somatic cell hybrids and consequently their positions on Chromosome 11 were not known. One proto-oncogene, Erbb-2 (analogous to the neu proto-oncogene), and one growth factor locus, Csfg (granulocyte colony-stimulating factor), which had not been mapped in the mouse were also localized on Chromosome 11 using the interspecific backcross mice. Recombination between Evi-2 and all proto-oncogene and growth factor loci was demonstrated, suggesting that Evi-2 may ultimately identify a new proto-oncogene involved in myeloid disease. This study revealed a number of interesting conserved linkage groups common to mouse and man.
