  • Title: Identification of endogenous retroviral sequences as potential donors for recombinational repair of mutant retroviruses: positions of crossover points.
    Author: Colicelli J, Goff SP.
    Journal: Virology; 1987 Oct; 160(2):518-22. PubMed ID: 3660592.
    Abstract:
    Mutants of Moloney murine leukemia virus carrying deletions in essential regions of the genome can revert after infection of mouse cells by recombination with endogenous retroviral sequences. We have identified cloned DNAs containing potential donor sequences for two such recombination events and determined the nucleotide sequences in the relevant regions. Comparison of these sequences with that of the original mutants and the revertant viruses allowed a determination of the crossover points that were used in formation of the revertants. Each crossover occurred in short stretches (17-24 bp) of perfect homology between the two parent sequences.
