RESUMO

Human cellular DNA contains two distinguishable families of retroviral related sequences. One family shares extensive nucleotide sequence homology with infectious mammalian type C retroviral genomes (T. I. Bonner, C. O'Connell, and M. Cohen, Proc. Natl. Acad. Sci. USA 79:4709-4713, 1982; M. A. Martin, T. Bryan, S. Rasheed, and A. S. Khan, Proc. Natl. Acad. Sci. USA 78:4892-4896, 1981). The other family contains major regions of homology with the pol genes of infectious type A and B and avian type C and D retroviral genomes (R. Callahan, W. Drohan, S. Tronick, and J. Schlom, Proc. Natl. Acad. Sci. USA 79:5503-5507, 1982; I. M. Chiu, R. Callahan, S. R. Tronick, J. Schlom, and S. A. Aaronson, Science 223:364-370, 1984). Analysis of the human recombinant clone HLM-2 has shown that the pol gene in the latter family is located within an endogenous proviral genome (R. Callahan, I. M. Chiu, J. F. H. Wong, S. R. Tronick, B. A. Roe, S. A. Aaronson, and J. Schlom, Science 228:1208-1211, 1985). We show that the proviral genome in HLM-2 and the related recombinant clone HLM-25 are located, respectively, on human chromosomes 1 and 5. Other related proviral genomes are located on chromosomes 7, 8, 11, 14, and 17.
