RNA Stability01:53

RNA Stability

36.1K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

Regulation of Expression at Multiple Steps

1.5K
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

Translational Regulation

766
Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...

pre-mRNA Processing

58.0K
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...

Area of Science:

  • Molecular Biology
  • Biochemistry
  • Cell Biology

Background:

  • RNA-binding proteins (RBPs) regulate gene expression and cellular metabolism.
  • While RBP functions are studied, the impact of their post-translational modifications (PTMs) remains less understood.
  • PTMs significantly diversify RBP functions beyond their canonical roles.

Purpose of the Study:

  • To summarize current knowledge on the consequences of PTMs on RBPs.

  • Literature review of studies on RBP PTMs.
  • Survey of experimental techniques for PTM identification (e.g., mass spectrometry, western blotting).
  • Examination of methods to assess functional consequences of PTMs.

Main Results:

  • PTMs increase the functional repertoire of RBPs.
  • Various experimental approaches exist to detect and analyze RBP PTMs.
  • Understanding PTMs is crucial for a comprehensive view of RBP roles.

Conclusions:

  • PTMs are critical regulators of RNA-binding protein function.
  • Further research into RBP PTMs will illuminate complex cellular regulatory networks.
