Transfer RNA as a source of small functional RNA
Journal of Molecular Biology and Molecular Imaging
|September 22, 2015
Summary
Transfer RNAs (tRNAs) are known for genetic translation but also yield functional small RNA fragments. These tRNA-derived fragments regulate diverse biological processes beyond their adapter role.
Area of Science:
- Molecular Biology
- Genetics
- RNA Biology
Background:
- Transfer RNAs (tRNAs) traditionally function as adapter molecules in genetic information translation.
- Emerging evidence reveals tRNAs are also precursors to small functional RNAs.
- These tRNA fragments are not random byproducts but specific molecules with biological roles.
Purpose of the Study:
- To review recent studies on tRNA fragments.
- To explore the molecular functions of tRNA fragments.
- To examine proteins interacting with tRNA fragments.
Main Methods:
- Biochemical analyses of tRNA fragments.
- Bioinformatic investigations of tRNA-derived small RNAs.
- Literature review of recent studies.
Main Results:
- tRNA fragments are generated from mature tRNAs and precursor transcripts.
- Specific tRNA fragments act as functional molecules in various biological processes.
- Interactions between tRNA fragments and proteins are crucial for their function.
Conclusions:
- tRNAs serve dual roles: translation adapters and sources of functional small RNAs.
- tRNA fragments are integral to biological processes beyond translation.
- Further research into tRNA fragments and their interacting proteins is essential for understanding tRNA biology.

Nucleic acids are the most important macromolecules for the continuity of life. They carry the cell's genetic blueprint and carry instructions for its functioning.
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...

10.3K
The pentose sugar in DNA is deoxyribose, while in RNA the pentose sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and a hydrogen on the deoxyribose's second carbon. The phosphate residue attaches to the hydroxyl group of the 5′ carbon of one sugar and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, which forms a 5′ to 3′ phosphodiester linkage.

15.2K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
