RESUMO

An endogenous retroviruslike DNA, B-26, was cloned from a BALB/c mouse embryo gene library by using a generalized murine leukemia virus DNA probe. Southern blot hybridization and nucleotide sequence analyses indicated that B-26 DNA might be a novel member of the GLN DNA family (A. Itin and E. Keshet, J. Virol. 59:301-307, 1986) which contains murine leukemia virus-related pol and env sequences. Northern analysis indicated that B-26-related RNAs of 8.4 and 3.0 kilobases were transcribed in thymus, spleen, brain, and liver tissues of 6-week-old BALB/c mice.
