Abstract
To investigate retroviral integration targeting on a nucleotide scale, we examined the base frequencies directly surrounding cloned in vivo HIV-1, murine leukemia virus, and avian sarcoma/leukosis virus integrations. Base preferences of up to 2-fold the expected frequencies were found for three viruses, representing P values down to <10(-100) and defining what appear to be preferred integration sequences. Offset symmetry reflecting the topology of the integration reaction was found for HIV-1 and avian sarcoma/leukosis virus but not murine leukemia virus, suggesting fundamental differences in the way different retroviral integration complexes interact with host-cell DNA.Entities:
