RNA localization is a widely utilized strategy employed by cells to spatially restrict protein function. In Saccharomyces cerevisiae asymmetric sorting of mRNA to the bud has been reported for at least 24 mRNAs. The mechanism by which the mRNAs are trafficked to the bud, illustrated by ASH1 mRNA, involves recognition of cis-acting localization elements present in the mRNA by the RNA-binding pro...
