Action mechanisms and research methods of tRNA-derived small RNAs
tRNA-derived small RNAs (tsRNAs), including tRNA-derived fragments (tRFs) and tRNA halves (tiRNAs), are small regulatory RNAs processed from mature tRNAs or precursor tRNAs.

Cryo-EM of elongating ribosome with EF-Tu•GTP elucidates tRNA proofreading
Ribosomes accurately decode mRNA by proofreading each aminoacyl-tRNA that is delivered by the elongation factor EF-Tu 1 . To understand the molecular mechanism of this proofreading step it is necessary to visualize GTP-catalysed elongation, which has ...

Discovery of Escherichia coli methionyl-tRNA synthetase mutants for efficient labeling of proteins with azidonorleucine in vivo [PDF]
Incorporation of noncanonical amino acids into cellular proteins often requires engineering new aminoacyl-tRNA synthetase activity into the cell. A screening strategy that relies on cell-surface display of reactive amino acid side-chains was used to ...

Quantitative analysis of tRNA abundance and modifications by nanopore RNA sequencing
Transfer RNAs (tRNAs) play a central role in protein translation. Studying them has been difficult in part because a simple method to simultaneously quantify their abundance and chemical modifications is lacking.

The tRNA identity landscape for aminoacylation and beyond
tRNAs are key partners in ribosome-dependent protein synthesis. This process is highly dependent on the fidelity of tRNA aminoacylation by aminoacyl-tRNA synthetases and relies primarily on sets of identities within tRNA molecules composed of ...

Novel layers of RNA polymerase III control affecting tRNA gene transcription in eukaryotes [PDF]
RNA polymerase III (Pol III) transcribes a limited set of short genes in eukaryotes producing abundant small RNAs, mostly tRNA. The originally defined yeast Pol III transcriptome appears to be expanding owing to the application of new methods.

METTL1 promotes hepatocarcinogenesis via m7G tRNA modification‐dependent translation control
Background N7‐methylguanosine (m7G) modification is one of the most common transfer RNA (tRNA) modifications in humans. The precise function and molecular mechanism of m7G tRNA modification in hepatocellular carcinoma (HCC) remain poorly understood ...

Mechanisms of ribosome recycling in bacteria and mitochondria: a structural perspective
In all living cells, the ribosome translates the genetic information carried by messenger RNAs (mRNAs) into proteins. The process of ribosome recycling, a key step during protein synthesis that ensures ribosomal subunits remain available for new rounds ...
