title: [Regions of human genome containing analogs of oncogenes and retrovirus genes. I. A family of c-mos genes and unusual structure of ORA-gp5 locus].
abstract: The structural organization of a number of recombinant phages previously selected from the human gene library has been studied. On the basis of comparison of physical maps and hybridization to cloned probes it was deduced that different human loci with the homology to v-mos are represented in lambda recombinants. The physical map of the cloned region of the human genome designated as ORA-gp5 was constructed. The sequences of three different genetical elements v-mos-related oncogene, mammalian type C retrovirus and Alu type repeat are interspersed in this structure. The hypothesis concerning the probable origin of this locus has been proposed. The mosaical structure of ORA-gp5 could be the result of the integration of mammalian retrovirus in the vicinity to c-mos gene with subsequent recombination and transposition. The resulting potentially oncogenic structure was later inactivated by the integration of Alu-type repeats.
