Insights

RNA polymerase II (RNAP II) transcription termination is poorly understood. This study examines RNAP II occupancy downstream of gene 3

Area of Science:

  • Molecular Biology
  • Gene Expression
  • Biochemistry

Background:

  • Eukaryotic gene transcription involves initiation, elongation, and termination.
  • Transcription termination is the least understood stage of gene expression.
  • RNA polymerase II (RNAP II) is the enzyme responsible for transcribing protein-coding genes.

Purpose of the Study:

  • To investigate the role of RNAP II occupancy downstream of gene 3' ends.
  • To explore the relationship between RNAP II occupancy, transcription termination, and mRNA 3' processing.

Main Methods:

  • Analysis of RNAP II occupancy patterns.
  • Correlation studies between downstream occupancy and termination efficiency.
  • Investigation of links to mRNA 3' end formation.

Main Results:

  • RNAP II occupancy downstream of the 3' end is linked to transcription termination.
  • This occupancy plays a role in the coordination of termination and mRNA processing.

Conclusions:

  • Understanding RNAP II downstream occupancy is crucial for deciphering transcription termination mechanisms.
  • RNAP II downstream occupancy is integral to the regulation of gene expression and mRNA maturation.

Eukaryotic RNA Polymerases

RNA Polymerase (RNAP) is conserved in all animals, with bacterial, archaeal, and eukaryotic RNAPs sharing significant sequence, structural, and functional similarities. Among the three eukaryotic RNAPs, RNA Polymerase II is most similar to bacterial RNAP in terms of both structural organization and folding topologies of the enzyme subunits. However, these similarities are not reflected in their mechanism of action.
All three eukaryotic RNAPs require specific transcription factors, of which the...

Transcription Attenuation in Prokaryotes02:42

Transcription Attenuation in Prokaryotes

Transcriptional attenuation occurs when RNA transcription is prematurely terminated due to the formation of a terminator mRNA hairpin structure.  Bacteria use these hairpins to regulate the transcription process and control the synthesis of several amino acids including histidine, lysine, threonine, and phenylalanine. Transcription attenuation takes place in the non-coding regions of mRNA.
There are several different mechanisms used to attenuate transcription. In ribosome mediated...
Termination of Translation01:44

Termination of Translation

The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

Chromatin Structure Regulates pre-mRNA Processing02:41

Chromatin Structure Regulates pre-mRNA Processing

In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.
The chromatin structure, especially...
