Summary
Target of rapamycin complex 1 (TORC1) regulates transfer RNA (tRNA) synthesis. Recent studies reveal intricate connections between TORC1 and tRNA, impacting eukaryotic cellular functions, particularly in yeast models.
Area of Science:
- Molecular Biology
- Cellular Biology
- Biochemistry
Background:
- Target of rapamycin (TOR) is a key kinase regulating cell growth and metabolism.
- Transfer RNA (tRNA) is crucial for mRNA translation and has diverse non-canonical functions.
- TOR complex 1 (TORC1) controls tRNA synthesis via RNA polymerase III.
Purpose of the Study:
- To review the regulatory links between TORC1 and tRNA.
- To highlight findings in yeast models like *Saccharomyces cerevisiae* and *Schizosaccharomyces pombe*.
Main Methods:
- Literature review of recent studies on TORC1 and tRNA interactions.
- Focus on regulatory mechanisms and cellular functions.
Main Results:
- TORC1 directly influences tRNA synthesis.
- Emerging evidence shows complex interplay between TORC1 and tRNA beyond synthesis.
- Yeast models provide key insights into these regulatory networks.
Conclusions:
- TORC1 and tRNA share significant regulatory connections.
- These connections are vital for eukaryotic cellular activities.
- Further research in yeast is crucial for understanding these pathways.

Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...

One of the unique features of tRNA is the presence of modified bases. In some tRNAs, modified bases account for nearly 20% of the total bases in the molecule. Altogether, these unusual bases protect the tRNA from enzymatic degradation by RNases.
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
