Abstract:
:The great majority of viral mRNAs in mouse C127 cells transformed by bovine papillomavirus type 1 (BPV) have a common 3' end at the early polyadenylation site which is 23 nucleotides (nt) downstream of a canonical poly(A) consensus signal. Twenty percent of BPV mRNA from productively infected cells bypasses the early polyadenylation site and uses the late polyadenylation site approximately 3,000 nt downstream. To inactivate the BPV early polyadenylation site, the early poly(A) consensus signal was mutated from AAUAAA to UGUAAA. Surprisingly, this mutation did not result in significant read-through expression of downstream RNA. Rather, RNA mapping and cDNA cloning experiments demonstrate that virtually all of the mutant RNA is cleaved and polyadenylated at heterogeneous sites approximately 100 nt upstream of the wild-type early polyadenylation site. In addition, cells transformed by wild-type BPV harbor a small population of mRNAs with 3' ends located in this upstream region. These experiments demonstrate that inactivation of the major poly(A) signal induces preferential use of otherwise very minor upstream poly(A) sites. Mutational analysis suggests that polyadenylation at the minor sites is controlled, at least in part, by UAUAUA, an unusual variant of the poly(A) consensus signal approximately 25 nt upstream of the minor polyadenylation sites. These experiments indicate that inactivation of the major early polyadenylation signal is not sufficient to induce expression of the BPV late genes in transformed mouse cells.
