Transfer RNAs (tRNAs) maintain translational fidelity through strict charging by their cognate aminoacyl-tRNA synthetase and codon:anticodon base pairing with the mRNA at the ribosome. Mistranslation occurs when an amino acid not specified by the genetic code is incorporated into a protein. Since al...

The endogenous RNA substrates of Translin-TRAX complexes (also known as C3POs) and how they regulate diverse biological processes remain unknown. Here we show that Translin and TRAX do not play a significant role in RNAi in the filamentous fungus Neurospora crassa. Instead, the Neurospora C3PO compl...

West Nile infectious clones were transfected with either SLA or tRNA. Viral RNA was extracted on days 3 and 4 post-transfection for sequencing. Shannon entropy and single nucleotide variants were analyzed to compare the samples.

Errors in protein synthesis are thought to be rare, yet cells representing the diversity of life tolerate greatly elevated levels of error. One source of translation error in humans are anticodon mutations in transfer RNAs (tRNAs). We found a tRNA Ser AGA -2-3 variant (G35A) that occurs in 2% of the...

Mistranslation, the mis-incorporation of an amino acid not specified by the “standard” genetic code, occurs in all cells. tRNA variants that increase mistranslation arise spontaneously and engineered tRNAs can achieve mistranslation frequencies approaching 10% in yeast and bacteria. The goal of this...

Small, non-coding RNAs control gene expression post-transcriptionally and play important roles in virus-host interactions. Within the liver, the microRNA (miRNA) miR-122 is essential for replication of hepatitis C virus (HCV), while repression of miR-148a by hepatitis B virus (HBV) may enhance tumor...

Altering the genetic code for applications in synthetic biology and genetic code expansion involves engineered tRNAs that incorporate amino acids that differ from what is defined by the “standard” genetic code. Since these engineered tRNA variants can be lethal due to proteotoxic stress, regulating ...

Prior work revealed nuclear-localized aminoacyl-tRNA synthetases (aaRSs) that checked newly synthesized tRNAs for charging before export to the cytoplasm. To reveal other functions, we sought to identify nuclear proteins that interact with arginyl-tRNA synthetase (ArgRS) in the nucleus. Serine/Arg...

Transfer RNAs (tRNAs) are the adaptor molecules required for reading of the genetic code and the accurate production of proteins. tRNA variants can lead to genome-wide mistranslation, the misincorporation of amino acids not specified by the standard genetic code, into nascent proteins. While genome ...

Mutations in tRNAs can lead to mis-incorporation of an amino acid into a growing polypeptide chain that differs from what is specified by the mRNA in a process known as mistranslation. As mistranslating tRNAs modify how the genetic message is decoded, they have potential as therapeutic tools to trea...
