Viruses with RNA Genomes01:29

Viruses with RNA Genomes

94
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Leaky Scanning02:28

Leaky Scanning

5.2K
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...

Types of RNA01:23

Types of RNA

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.

RNA Interference01:23

RNA Interference

26.3K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

46.5K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Conjugated Proteins02:50

Conjugated Proteins

18.5K
Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

Area of Science:

  • Virology
  • Molecular Biology
  • Bioinformatics

Background:

  • Coronaviruses have caused three major outbreaks in recent decades, posing significant public health threats.
  • Viral life cycles rely on interactions between viral and host molecules, particularly virus RNA and host proteins (IVRHP).
  • Understanding IVRHP is crucial for both viral propagation and host defense against pathogenicity.

Purpose of the Study:

  • To construct a comprehensive database (CovInter) detailing interactions between coronavirus RNAs and host proteins.
  • To provide a centralized resource for studying the molecular mechanisms of coronavirus infection.
  • To facilitate the discovery of novel antiviral therapies by elucidating virus-host molecular dynamics.

Main Methods:

  • Development of a novel database, CovInter, specifically for IVRHP data.
  • Unambiguous characterization of virus RNA-host protein interactions within the database.
  • Inclusion of experimentally validated biological functions for host proteins involved in viral infection.
  • Systematic quantification of differential expression patterns of key host proteins before and after infection.

Main Results:

  • CovInter uniquely characterizes IVRHP, offering a detailed view of these critical molecular interactions.
  • The database comprehensively lists experimentally validated functions of numerous host proteins vital during coronavirus infection.
  • Differential expression patterns of key host proteins are systematically quantified, providing insights into host responses.

Conclusions:

  • CovInter addresses the urgent need for a dedicated database of IVRHP data.
  • This resource is expected to significantly advance our understanding of the 'molecular arms race' between coronaviruses and hosts.
  • CovInter is anticipated to be a valuable tool for accelerating the development of new antiviral strategies.
