Types of RNA

74.0K
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.

Ribosomal RNA Synthesis

15.3K
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,...

Bacterial RNA Polymerase

33.9K
Unlike eukaryotes, bacteria use a single RNA Polymerase (RNAP) to transcribe all genes. The different subunits of bacterial RNAPhave distinct functions. The multisubunit structure of the bacterial RNAP helps the enzyme to maintain catalytic function, facilitate assembly, interact with DNA and RNA, and self-regulate its activity.
In most genes, the transcription site is a single base present upstream of the coding sequence. Though RNAP is a catalytically efficient enzyme, it does not recognize...

Area of Science:

  • Molecular Biology
  • Genetics
  • Microbiology

Background:

  • Traditional mycobacterial gene regulation studies focus on proteins.
  • Noncoding RNA (ncRNA), RNA not translated into protein, is increasingly recognized for its regulatory functions.
  • ncRNA encompasses various types, including ribosomal RNA (rRNA), transfer RNA (tRNA), and regulatory RNA.

Purpose of the Study:

  • To review the emerging information on the presence and abundance of different types of noncoding RNA in mycobacteria.
  • To highlight the expanding role of regulatory RNA in mycobacterial gene regulation.
  • To shift the perspective from a protein-centric view to include ncRNA.

Main Methods:

  • Literature review of existing research on mycobacterial noncoding RNA.
  • Analysis of the known functions and characteristics of various ncRNA species.
  • Discussion of the implications of ncRNA in mycobacterial gene regulation.

Main Results:

  • Noncoding RNA, particularly regulatory RNA, plays a significant role in mycobacterial gene regulation.
  • Regulatory RNA can interact with messenger RNA (mRNA) or proteins to control gene expression.
  • Mycobacteria possess a diverse population of ncRNA, including 5' and 3' untranslated regions.

Conclusions:

  • Noncoding RNA is a crucial component of mycobacterial gene regulation, acting as a key player in environmental responses.
  • Further research into mycobacterial ncRNA is essential to fully understand gene regulatory networks.
  • The "dark matter of gene regulation" in mycobacteria is increasingly being illuminated by ncRNA studies.
