tRNAs are unique among various RNAs in that they shuttle between the nucleus and the cytoplasm, and their localization is regulated by nutrient conditions. Although nuclear export of tRNAs has been well documented, the import machinery is poorly understood. Here, we identified Ssa2p, a major cytoplasmic Hsp70 in Saccharomyces cerevisiae, as a tRNA-binding(More)
A part of eukaryotic tRNA genes harbor an intron at one nucleotide 3' to the anticodon, so that removal of the intron is an essential processing step for tRNA maturation. While some tRNA introns have important roles in modification of certain nucleotides, essentiality of the tRNA intron in eukaryotes has not been tested extensively. This is partly because(More)
