Proto-oncogene homologous sequences in the sea urchin genome

Abstract:
Using probes specific for several oncogenes/proto-oncogenes we have performed gel blot hybridization analyses of genomic DNA isolated from the sea urchin Strongylocentrotus droebachiensis. Probes prepared from v-erbB, v-myc, c-myb and v-fps were found to hybridize with discrete fragments of HindIII digested genomic DNA. In contrast, probes prepared from v-abl, v-fos, v-sis, v-src, and v-mos either hybridized with multiple fragments, indicating non-specific binding, or failed to hybridize at all above background levels. These results clearly demonstrate the presence of proto-oncogene homologous sequences in the sea urchin genome.
