pubmed:abstractText |
The RNA14 and RNA15 gene products have been implicated in a variety of cellular processes. Mutations in these genes lead to faster decay of some mRNAs and yield extracts that are deficient in cleavage and polyadenylation in vitro. These results suggest that the RNA14 and RNA15 gene products may be involved in both adenylation and deadenylation in vivo. To explore the roles of these gene products in vivo, we examined the site of adenylation and the rate of deadenylation for individual mRNAs in rna14 and rna15 mutant strains. We observed that the rates of deadenylation are not affected by lesions in either the RNA14 or the RNA15 gene. This result suggests that the proteins encoded by these genes are not involved in regulation of the deadenylation rate. In contrast, we observed that the site of adenylation for the ACT1 transcript can be altered in these mutants. Interestingly, we also observed that mutation of the poly(A) polymerase gene altered the site of ACT1 polyadenylation. These observations suggest that the RNA14, RNA15, and PAP1 proteins are involved in poly(A) site choice. This alteration in poly(A) site choice in the rna14 mutant can be corrected by the ssm4 suppressor, indicating that this suppression acts at the level of polyadenylation and not by slowing mRNA degradation.
