Insights

This study retraction concerns an article on PERK's role in alphavirus nonstructural protein translation. The journal Viruses has formally retracted the publication due to significant concerns.

Area of Science:

  • Virology
  • Molecular Biology
  • Cellular Biology

Background:

  • Alphaviruses are RNA viruses that cause significant human diseases.
  • Nonstructural protein synthesis is essential for viral replication.
  • The unfolded protein response pathway, including PERK, plays a role in cellular stress and protein synthesis.

Purpose of the Study:

  • To investigate the role of Protein Kinase R (PKR)-like ER kinase (PERK) in alphavirus nonstructural protein translation.
  • To determine if PERK is essential for the efficient synthesis of viral proteins.
  • To understand the mechanisms by which PERK influences alphavirus replication.

Main Methods:

  • Utilized cell culture models infected with alphaviruses.
  • Employed techniques such as Western blotting and quantitative reverse transcription PCR.
  • Investigated the effects of PERK inhibition or activation on viral protein levels.

Main Results:

  • The original study suggested PERK is critical for alphavirus nonstructural protein translation.
  • Subsequent analysis and concerns led to the retraction of these findings.
  • The precise role of PERK in alphavirus replication remains an area for further investigation.

Conclusions:

  • The article "PERK Is Critical for Alphavirus Nonstructural Protein Translation" has been retracted by the journal Viruses.
  • The retraction signifies that the published findings are no longer considered valid.
  • Further research is needed to clarify the relationship between PERK and alphavirus nonstructural protein synthesis.

Initiation of Translation02:33

Initiation of Translation

Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

Leaky Scanning02:28

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

The Unfolded Protein Response01:37

The Unfolded Protein Response

The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
