Abstract:
Avian leukosis viruses (ALVs) that induce rapid B-cell lymphomas integrate into the c-myb gene and produce an ALV-myb read-through RNA, which is spliced to produce a truncated Myb protein. The genetic determinants of such recombinant ALVs have been mapped to a 42-nt deletion within the gag gene. This deletion increases splicing efficiency since it is located within a negative regulator of splicing. We propose that the deletion leads to increased production of Myb protein by increasing splicing of an ALV-myb pre-mRNA.
