TRR4

L000003654, tR(CCG)L
Arginine tRNA (tRNA-Arg), predicted by tRNAscan-SE analysis; single essential nuclear tRNA gene containing the tDNA-anticodon CCG (presumably CCG in the mature tRNA), decodes CGG codons into arginine, one of 19 nuclear tRNAs for arginine; correct folding and efficient aminoacylation require Lhp1p

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Publication

The La protein functions redundantly with tRNA modification enzymes to ensure tRNA structural stability.

Copela LA, Chakshusmathi G, Sherrer RL, Wolin SL

Although the La protein stabilizes nascent pre-tRNAs from nucleases, influences the pathway of pre-tRNA maturation, and assists correct folding of certain pre-tRNAs, it is dispensable for growth in both budding and fission yeast. Here we show that the Saccharomyces cerevisiae La shares functional redundancy with both tRNA modification enzymes and other proteins that contact tRNAs during their biogenesis. La is ... [more]
